We like to think of memory as proof of who we are. The things we remember become the architecture of our identity, yet beneath that structure lies something quieter, more fragile, and perhaps more vital: the things we forget.
Forgetting has always been treated as the mind’s flaw. A smudge in the lens. But what if it’s the very process that keeps the lens clear?
The Brain’s Gentle Refusal
Neuroscience describes memory as a process of constant revision. The hippocampus stores and reshapes what we take in, then loosens its grip when something no longer serves the present (Squire, 2009).
Researchers in Toronto proposed that the brain forgets to survive. Without that ability, consciousness would collapse under its own weight (Bjork, 1975). We would be unable to tell what matters. The mind that never forgets cannot change its mind.
Every day, thousands of synaptic connections fade, but traces remain as pathways that strengthen when we return to them. The rest dissolve into the white noise of experience, making room for new learning, new meaning, and new selves (Kandel, 2006).
The Poetry of Impermanence
When we revisit a memory, we rewrite it. The scene shifts, colors dull or brighten, dialogue rearranges itself (Loftus, 2005). What we call memory is really imagination tethered to a few truths.
There is something sacred about this impermanence. It protects us from being trapped in yesterday’s version of ourselves. It allows pain to lose its sharpness, allows love to change shape without vanishing. Forgetting is not the opposite of remembering; it is how remembering stays bearable (Hardt, 2008).
A Mind that Learns to Release
To live fully may mean learning to let thoughts fade without resistance. We do not abandon what we forget; we carry the echo of it. The brain understands this long before we do. It edits with care, choosing what we are ready to carry forward (McGaugh, 2000).
Some cultures have long understood this rhythm. The Japanese concept of mono no aware—the bittersweet awareness of impermanence—captures the beauty of forgetting. The ancient Greeks linked memory to Mnemosyne, the mother of the Muses, yet they also revered Lethe, the river of forgetting, as the path to peace (Assmann, 2011).
The self that remembers everything would have no room to grow, and the one who forgets too easily would lose coherence. So we exist between the two in a delicate equilibrium of holding and release.
The Human Art of Letting Go
Forgetting is not a failure of intellect but a condition of grace. It gives us the courage to begin again, to rebuild understanding without the burden of total recall. The mind renews itself in the spaces it empties.
Perhaps this is what it means to be human: to remember just enough to love the world, and to forget just enough to forgive it.

You open your phone to check one thing. Fifteen minutes later, you’ve replied to two texts, saved a recipe, watched half a video, and somehow never done what you meant to do in the first place. When you finally put it down, your mind still hums with half-formed tasks.
Our brains were never built to live in open tabs.
Psychologists call this the Zeigarnik Effect: the tendency to remember unfinished or interrupted tasks more vividly than completed ones. It’s why a forgotten to-do list nags at you more than the dozens of items you’ve already crossed off. The mind craves closure the way the lungs crave air.
But because our world never truly ends, that craving becomes a quiet torment.
II. The Zeigarnik Effect: The Brain’s Unfinished Symphony
In the 1920s, psychologist Bluma Zeigarnik noticed something curious: waiters remembered unpaid orders better than completed ones. Once the bill was settled, the details seemed to vanish from memory.
Modern neuroscience has since confirmed her insight. Our brains generate dopaminergic tension when something is incomplete, which is a kind of cognitive itch that pushes us toward resolution. Completion relieves the tension, but only for a moment. Soon the mind looks for the next unfinished thing to chase.
The internet runs on this loop. “Next episode” buttons, red notification dots, infinite scrolls, and each one a tiny cliffhanger engineered to keep us suspended in the half-finished.
III. Decision Fatigue: The Cost of Constant Choice
Every unfinished thought competes for energy. Add a thousand small choices, what to wear, text, eat, or watch, and the brain begins to tire. The result is decision fatigue, the invisible tax of modern life.
Research by Roy Baumeister and colleagues shows that every decision draws from the same cognitive pool we use for focus and self-control. As the day goes on, that pool drains.
We call it burnout or lack of motivation, but really it’s just the cost of too many open tabs. Every half-done task is a leak in the mind’s attention, and we are slowly running dry.
IV. The Digital Age: Infinite Loops, Finite Minds
Our devices have become machines for fragmentation.
Psychologists describe something called cognitive residue, the trace of attention left on a task even after we’ve moved on. Each switch between apps or thoughts leaves behind a faint echo, blurring our focus until nothing feels whole.
This state of half-presence has a name: psychological entropy. It’s the discomfort that arises when the mind’s order dissolves into chaos. Modern media feeds that entropy, keeping us suspended in the tension of what’s next.
In the economy of attention, our unfinished thoughts have become the most valuable commodity.
V. Creativity and the Gift of the Unfinished
Not all incompletion is a curse. The same tension that drives distraction can also spark creativity.
Writers, scientists, and musicians have long relied on the “productive pause”, defined as the act of stepping away to let the subconscious take over. Neuroscience calls this the incubation effect, and it’s tied to the default mode network, the system that activates when we rest, wander, or daydream.
Unfinished ideas incubate. They evolve in silence. They grow roots while we sleep or walk or stare into space. To pause is to make room for the unseen work of the mind.
VI. The Youth Paradox: Overstimulated and Underslept
For teens and young adults, this cycle is especially intense. School, social media, and constant performance pressure combine into a mental marathon without finish lines. Every notification and assignment becomes another open loop.
This chronic stimulation bleeds into sleep, disrupting the brain’s nightly ritual of sorting, storing, and restoring. During REM and slow-wave sleep, the brain organizes memory, cleanses itself of metabolic waste, and closes the loops we left open during the day.
When sleep is cut short, those loops remain unclosed. We wake up cluttered and foggy in a generation living in mental overdrive yet feeling perpetually unfinished.
We fall asleep simply to tidy the chaos our waking minds cannot.
VII. Closing the Loop: The Art of Choosing Less
The great misconception, especially among the young and ambitious, is that mental toughness means constant motion. In reality, clarity often comes from subtraction.
Choosing less doesn’t equate to caring less. It is just to care more precisely.
We can’t close every loop, nor should we. The goal is to know which ones deserve our attention and which can remain gracefully unfinished. The brain, after all, thrives on both tension and rest. One highly effective habit you can try is to establish some sort of “second brain” for yourself; a notebook, a note-taking app, or a post it that holds all the daily scribbles you realize you must accomplish at some point.
To live deliberately is to choose which threads to tie and which to let drift, trusting that some of life’s most meaningful work happens in the quiet space between.
In a world obsessed with doing more, perhaps the wisest act is simply to finish less, but in doing so, finish more fully.
Sixty days left in 2025. That’s enough time to either coast through the end of the year or to reprogram how you think, focus, and act. The truth is, your brain remains remarkably adaptable.
This is not about resolutions. It is about neuroscience and the quiet biological fact that change is built on repetition and reflection.
1. The Myth of the Big Reset
We love the fantasy of transformation: new notebooks, gym sign-ups, the illusion that change begins on command. But real rewiring does not happen that way.
Neuroscience shows growth is not a switch but a slow layering of signals. Every day your brain listens to your behavior and adjusts. Patterns of thought and action, repeated often enough, become automatic pathways. You do not “flip” into a new self. You train your neurons into one.
Mindset shift: Stop thinking in resolutions. Start thinking in repetitions.
The 1% Rule
Improve by one percent each day – one percent more focus, one percent more rest, one percent more presence. After sixty days, that is not sixty percent improvement. Compounded, it is exponential. Neural networks strengthen with consistency, not drama.
2. The Science of Rhythm: Finding Your Neural Schedule
Your perfect day is already coded into your biology. The brain runs on circadian (daily) and ultradian (hourly) rhythms that govern alertness, creativity, and fatigue. Ignoring those rhythms is like rowing against a current: possible, but exhausting.
The Focus Framework
Track your natural peaks for three days. Note when your brain feels sharpest and when it fogs.
Protect your high-focus window for deep work – writing, studying, thinking.
Use low-focus hours for logistical tasks and errands.
Rest every 90 minutes to align with attention cycles and help neurotransmitters reset.
Once you align your schedule to your neural rhythm, productivity will come more easily, not just from sheer willpower.
3. The Novelty Principle: Reawakening Dormant Circuits
The brain thrives on surprise. Novelty (new experiences, ideas, or environments) activates dopamine pathways tied to curiosity and learning. When everything feels repetitive, the brain goes into predictive mode and attention fades.
Novelty is not merely entertainment. It is biological nutrition for attention.
Small Ways to Add Novelty
Change your study or commute route.
Read an author or genre you rarely choose.
Listen to a podcast outside your usual subjects.
Rearrange your workspace or swap your morning routine.
Each small disruption forces your sensory and motor cortices to re-coordinate, for more whimsy in life.
4. The Attention Economy and the Art of Recovery
Your attention is your most limited neural currency. Every task switch or phone check spends dopamine and glucose, the fuels of focus. Constant context switching leads to micro self-interruption that accumulates fatigue.
The Two-Window Method
Deep Work Window: One 90-minute period daily for immersion. One task, zero notifications.
Restorative Window: 20 minutes of real rest after deep work: walking, breathing, or silent reflection. No screens.
During rest, your brain consolidates learning.
5. Sleep: The Night Shift of the Brain
Sleep is not optional. During deep sleep, brain cleaning processes remove metabolic waste. During REM sleep, emotional and sensory memories get integrated into long-term patterns.
The Rewind Ritual
Thirty minutes before bed, dim lights and screens.
Write three lines about what you learned or noticed today.
Visualize your brain sorting and storing those experiences overnight.
After sixty days, this simple ritual strengthens hippocampal memory consolidation and emotional balance.
6. The Emotional Brain: Reframing Stress
Stress in small doses sharpens focus and motivation; chronic stress is what harms the brain. The trick is to reframe stress as signal, not threat.
The Stress Reframe
Name it: say to yourself, “My body is preparing me.”
Breathe in for four counts, out for six to activate the calm response.
Turn the task into curiosity: ask, “What is this trying to teach me?”
This practice trains the prefrontal cortex to interpret pressure as stimulation. Over time, that narrative becomes automatic and resilience grows at the circuit level.
7. Reflection: The Architecture of Identity
Your brain learns not only from action, but from what it notices about action.
The Nightly Check-In
What did I learn today about the world or about myself?
What felt meaningful?
What drained me, and why?
Who made me smile?
Five minutes of nightly journaling rewires self-awareness. You begin to see patterns in the quiet beginning of self-creation.

9. The Quiet Revolution
When the year ends, the world may look the same. But beneath the surface, your brain will have changed. You will return to focus faster. You will respond to stress with more equanimity. You will notice life more clearly.
That is the real miracle of the human brain: it is always becoming. And sixty days is enough time to begin again.
You got this. Now take the steps, no matter how small, and finish the year strong.
Your perfect schedule is already built in to your brain, here’s how to find it.
Ever wonder what a perfect day would look like if your brain actually cooperated? As a student, I’ve spent countless mornings staring at my planner, wondering how to get everything done without going crazy. Between lectures, homework, and the never-ending influx of notifications, it often feels impossible to stay focused or energized. Luckily, neuroscience has some surprisingly practical answers, tools and insights you can actually use to design a day that works with your brain, not against it.
Sleep: The Non-Negotiable Starter
Your neurons are night-shift workers. They do not take coffee breaks. Deep sleep is when your brain consolidates memory, prunes connections, and basically declutters itself. Skipping it is like trying to run your laptop with twenty tabs open and battery at 10%. For students, this means late-night cramming is usually self-defeating. Your brain might get the homework done but it will forget half of it by tomorrow. I know it’s hard, but please aim for 7-9 hours and try to stick to a consistent schedule. Your future self will thank you.
Timing Matters
Your brain does not operate at full power all day. For most people, mornings are best for focus-heavy tasks like writing essays or solving math problems. Afternoons are better for lower-stakes or social tasks because your alertness naturally dips. Evenings, surprisingly, are when creativity peaks, making it the perfect time for brainstorming, art, or revising your philosophy blog. Mapping your most important tasks to your brain’s natural rhythms is like scheduling meetings with your most demanding client, which happens to be yourself.
Work in Bursts
Attention is a finite resource. The brain has ultradian rhythms, cycles of about 90-120 minutes of high alertness followed by a dip. Working for long stretches without a break is like driving a car without refueling. Try focusing for 25-50 minutes, then take a 5-10 minute break. Walk around, stretch, or just stare out the window. Your neurons actually perform better when given a pit stop.
Tiny Wins and Dopamine
Dopamine is the brain’s reward molecule. It helps you pay attention, remember things, and feel good while doing them. Checking your phone releases dopamine, which is why it’s so addictive. You can hack the system by rewarding yourself for small accomplishments. Finish a paragraph or send an important email, then treat yourself to a song or a snack. These micro-rewards keep motivation high without falling into the trap of procrastination disguised as productivity.
Flow Is Your Friend
Contrary to popular belief, your brain cannot multitask. It can only switch attention quickly, leaving a trail of incomplete thoughts. Flow happens when your skill level matches the challenge in front of you. That sweet spot where time disappears is the perfect zone for productivity. Batch similar tasks, eliminate notifications, and dive in without guilt. Flow loves focus, and your brain will thank you with higher quality work and less stress.
Move Your Body
Even a 10-minute walk or a few stretches trigger brain-derived neurotrophic factor, or BDNF. This protein helps neurons grow and stay flexible. Movement literally helps your brain work better. Try walking to class, stretching between study sessions, or even dancing in your room. It’s scientifically proven to reduce stress while boosting energy.
Reflect and Reset
Reflection is where your brain consolidates memory, processes mistakes, and primes itself for tomorrow. Journaling, meditating, or just mentally replaying the day helps you learn from experience. 5 minutes of reflection at the end of the day can provide actionable insights and make tomorrow feel a little less chaotic.
The Takeaway
A perfect day is not about cramming more hours into your schedule or pretending to be a productivity robot. It is about designing your environment, your tasks, and your mindset around how your brain actually works. Sleep, flow, movement, timing, rewards, and reflection are the ingredients. Layer them thoughtfully and your day becomes less of a struggle and more of a rhythm. With a little planning and a lot of understanding of your own brain, students (like you and me) can actually make each day feel productive, energizing, and maybe even a little magical.
You got this! Now go take the steps, no matter how small, to achieve your goals!
Every night, while the world fades into quiet, your brain gets to work. Far from idle, it runs a shift that scientists are still trying to understand: sorting, repairing, and processing the fragments of the day into something coherent.
The Science of Sleep and Memory
Sleep is not passive rest. It’s a complex biological process with stages as distinct as scenes in a film. During slow-wave sleep (SWS), the brain replays recent experiences, transferring short-term memories from the hippocampus to the neocortex (Rasch & Born, 2013). This “neural replay” consolidates learning, preserving only what matters most and pruning what doesn’t.
Then comes REM sleep, where neurons fire in irregular bursts, the amygdala lights up, and logic takes a backseat. This is the stage of vivid dreaming, where emotions, creativity, and subconscious processing take center stage. REM doesn’t just solidify memories; it integrates them, connecting new information with old to form insight (Walker & Stickgold, 2010).
In short, your dreams might be your brain’s way of telling stories about who you’re becoming.
Why Dreams Feel So Real
During REM, the brain’s prefrontal cortex, responsible for logic and self-awareness, quiets down. Meanwhile, visual and emotional centers fire intensely, creating immersive experiences that feel convincing even as they defy physics. This is why you can fly, cry, or argue with someone who doesn’t exist.
Neurologically, dreams may serve as emotional regulation. They allow us to revisit unresolved experiences in a safe mental space. Matthew Walker calls it “overnight therapy,” where the brain softens emotional edges while preserving the memory itself (Walker, 2017).
When the Night Shift Is Cut Short
The problem is that modern life interrupts this process. Teens and young adults (like me), those who need deep sleep most, are sleeping less than ever. Tell me about it. School starts early, screens glow late, and the myth of productivity glorifies being tired by giving your all every day. Yet chronic sleep deprivation can reduce hippocampal function, impair decision-making, and weaken emotional control (Curcio et al., 2006).
Without enough REM and deep sleep, the brain’s night shift never finishes its work, resulting in fuzzier memories, mood swings, and a subtle sense of disconnection.
What It Means for Young Minds
For high schoolers and college students, sleep is often treated like a luxury, not a necessity. But neuroscience argues the opposite. The hours you spend asleep aren’t wasted. They’re when your brain learns and grows. Every dream, no matter how strange, reflects a network of neurons trying to make sense of you and your world. And there are so many more benefits outside of what sleep does to your brain that should be emphasized.
The takeaway isn’t to chase every dream for meaning. It’s to respect the process that creates them. Let your brain do its night shift. Turn off the lights. Trust that in the quiet, it’s still working. Because it is organizing, remembering, and rebuilding who you’ll be when you wake.

There is a strange calm that washes over you when lo-fi beats fill your headphones while studying. There is an unspoken connection in a crowded concert hall when thousands sway together. These experiences are more than just beautiful; they are neural. Music has the power to synchronize brain activity within and across individuals, aligning thoughts, emotions, and attention in ways we are only beginning to understand.
Neural Synchronization
Neuroscientists call this neural synchronization. When your brain hears a beat, its neurons start to oscillate in rhythm with it. Note that this is not just happening in your auditory cortex; it spreads to motor regions, the cerebellum, and prefrontal areas involved in focus and expectation.
Even more fascinating, people listening to the same music often show inter-brain synchrony. Studies reveal that their brainwaves can match up in time and frequency, creating a subtle shared experience of connection (Lindenberger et al., 2009; Sänger et al., 2012). In a very real sense, music can make our minds move together.
Binaural Beats & the Brain’s Rhythmic Flexibility
Neural sync isn’t just for concerts. Binaural beats use two slightly different tones, one in each ear, tricking the brain into hearing a third, imagined beat. This auditory illusion can nudge your brain into different rhythms, from alpha waves that calm you to beta waves that sharpen your focus (Lane et al., 1998; Goodin et al., 2012).
Listening to binaural beats in specific frequency ranges can modulate brain states. Alpha-range beats (8–12 Hz) are associated with relaxation, while beta-range beats (13–30 Hz) may enhance focus or alertness (Lane et al., 1998; Goodin et al., 2012). While research is still exploring the effects, the principle is simple: our brains are rhythm machines, and sound is a powerful conductor.
Why It Matters
When our brainwaves align with others through shared sound, the boundaries of self and other blur. The same mechanisms that allow a drummer to keep time also underlie the neural foundations of empathy and cooperation. It explains why music feels social even in solitude. When our neurons align with rhythm, whether in a concert, a quiet practice session, or through binaural beats, we experience a sense of belonging.
Music organizes our inner worlds and aligns them with others, proving that even when we’re alone, our brains are seeking resonance.

You open the fridge, determined to make something healthy. Ten minutes later, you’re staring at leftovers, wondering if cereal counts as dinner.
It’s not laziness or indecision, it’s biology. Every choice you make throughout the day, from what to wear to which email to answer first, draws from a limited supply of mental energy. By evening, your brain is running on fumes.
This invisible drain, known as decision fatigue, reveals something fascinating about how the human brain works. At it’s core, decision fatigue is not a failure of willpower but a natural consequence of how our neurons process choices. The problem is that modern life was not built with that biology in mind.
Understanding decision fatigue is not simply about improving productivity; it is about recognizing the biological limits of human cognition in a world that demands constant engagement.
The Brain’s Energy Economy
The human brain weighs roughly three pounds but consumes nearly 20% of the body’s energy at rest (Raichle & Gusnard, 2002). Most of this energy supports synaptic activity, which is the electrochemical communication between neurons we need for thought and judgement.
The prefrontal cortex, responsible for executive functions such as reasoning and self-control, is particularly energy-intensive. When glucose levels decline in this region, the brain’s capacity for self-regulation and decision-making drops sharply (Gailliot et al., 2007). Neuroscientist Matthew Lieberman describes this as a “neural budget” that depletes with use. Neural budget is a concept that many struggle with because they believe willpower will be enough for difficult tasks and maintaining drive throughout extended periods.
Every choice, even trivial ones like selecting a meal, engages these same neural pathways. As the day progresses, neurons in the prefrontal cortex communicate less efficiently, and the brain shifts from deliberate reasoning to what psychologists call heuristic processing, defined as simpler, faster decision-making strategies (Kahneman, 2011).
The Psychology of Overchoice
Furthermore, modern environments amplify this biologically induced limit of decision-making capacity. Psychologist Barry Schwartz famously described this as “The Paradox of Choice”. Essentially, the more options we face, the more anxious and dissatisfied we become (Schwartz, 2004).
Research at Stanford University found that individuals confronted with extensive choices, such as 24 flavors of jam, were significantly less likely to make a purchase than those offered only six options (Iyengar & Lepper, 2000). Each additional alternative increases cognitive load and prolongs the decision process, drawing more energy from an already taxed brain.
Unlike physical exhaustion, decision fatigue builds invisibly. It often manifests as irritability, procrastination, or emotional numbness. These are the quiet symptoms of a brain that has simply made too many choices.
The Dopamine Trap
Dopamine, the neurotransmitter responsible for motivation and reward, also plays a role in this cycle. Each decision completed, no matter how small, triggers a small release of dopamine, reinforcing the behavior (Berridge & Kringelbach, 2015). But when the brain faces an unrelenting stream of micro-decisions (for me, notifications, texts, playlists, which task to start first), its dopamine system becomes desensitized.
This desensitization blurs the line between meaningful and trivial choices, flattening emotional reward and leaving us less motivated. Satisfaction flatlines to dull routine, an effect researchers call hedonic adaptation (Brickman & Campbell, 1971). Thus, even enjoyable activities, like choosing what to eat out, begin to feel burdensome.
Modern Life as a Cognitive Overload Experiment
From an evolutionary perspective, the human brain evolved for scarcity, not abundance. Early humans only had to make a few high-stakes decisions per day: when to hunt, where to seek shelter, whom to trust. But today, an average person makes hundreds of decisions before noon. (Albeit not very high-stakes ones, but we are fooled into believing that they are.)
Cognitive neuroscientist Daniel Levitin argues that “each shift in attention sets off metabolic processes that deplete the brain’s neural resources.” (Levitin, 2014) In essence, the constant switching of modern life between countless microtasks induces a continuous state of mental taxation.
Modernity, then, has become a sort of cognitive overload experiment with us as the subjects. As a result, we are fatigued, less creative, less empathetic, and less patient overall. Our higher-order cognition is becoming subtly eroded.
The Case for Cognitive Minimalism
Emerging research suggests that the antidote to decision fatigue is not more efficency, but fewer choices. Cognitive minimalism, the deliberate simplification of daily decisions, conserves neural energy for more meaningful cognitive work (Goyal et al., 2018).
Small interventions, such as automating low-stakes tasks, like Einstein or Steve Jobs wearing the same outfits every day, can significantly reduce cognitive load. This aligns with neural conservation theory: the idea that the brain strategically limits effort to preserve long-term function (Kurzban et al., 2013).
Conclusion: When Simplicity Becomes Intelligence
In popular culture, especially among teenagers and young adults, mental endurance is often glorified as a sign of strength. The ability to “push through” fatigue, multitask endlessly, and make rapid decisions is frequently mistaken for resilience. Yet neuroscience paints a different picture.
Decision fatigue is more than a productivity challenge; it is a reflection of how our cognitive systems evolved. The mechanisms that once helped us survive now collide with an environment of endless stimulation.
This misunderstanding matters. Many young people internalize the idea that slowing down is a weakness, that stepping back means falling behind. In reality, the opposite is true. Rest, constraint, and deliberate choice are not escapes from mental rigor but expressions of it. Each time we choose less, whether by limiting options, simplifying routines, or pausing before the next decision, we conserve cognitive energy and restore clarity.
Ultimately, the neuroscience of decision fatigue reveals an overlooked truth: wisdom is not measured by how much we do, but by how thoughtfully we choose what to do next.

If you’ve been wondering what I’ve been up to lately, here’s the honest answer: college applications.
That’s it. That’s the post.
Okay, not really. But it certainly feels that way. Every day’s been a mix of writing essays, editing essays, thinking about essays, and then trying to remember what I was like as a human before essays existed.
What It’s Taught Me
Weirdly, the process has made me more organized than I’ve ever been. I’ve learned how to actually manage time. It’s an improvement over just making to-do lists that never end. I’ve learned how to tell my own story in a way that feels authentic instead of trying to sound impressive.
And I’ve learned that writing about yourself is harder than any AP class.
The Reality Check
It’s not glamorous. There are nights when I’m staring at my computer at 1 a.m. avoiding cliché words or phrases like the plague. There are days when I want to throw my laptop out the window.
But then there are also those small wins: when a sentence finally clicks, or when a teacher or friend gives you a pep talk.
Why It’s Worth It
Somewhere between the drafts and the deadlines, I’ve realized this isn’t just about getting into a school. It’s about slowing down and figuring out who I actually am when no one’s grading me for it.
So yeah. That’s what I’ve been working on. A lot of writing. A lot of reflecting. And a lot of tea.
