I nodded to her. Then I eyed Maeve. "What about you? Holding anything back?" "I want to take you to my bower, wizard," Maeve said, and licked her lips. "I want to do things to you that give you such pleasure your brain bleeds." "Uh," I said. Her foxlike smile sharpened. "Also," she said, "my people are about to attempt to kill you.

The idea is that one day a week, you need to get your mind in a different mode, you need to not work. Every week, your brain—and your soul—needs to be reset.

We have the power as individuals to create a different perspective. We can physically rewire our brains to see our work and lives in a more positive light. We can reduce our stress and increase our peace and happiness. We can use our minds to change our brains for a better life.

So, maybe we’re the generation of the selfie, but we’re also the generation that grew up in a tainted, Photoshopped world with every impossible beauty standard shoved down our throat through a tube because eating has become a guilty pleasure and condemning beauty ideals won’t go straight to our thighs. And if, by chance, we are able to destroy the demons that you’ve planted inside of us with your constant advertisements and rules that play behind our eyelids and take root in our brains, then let us take our fucking pictures and capture that moment when we felt beautiful because all this world has taught us is that our beauty is the greatest measure of our worth. Scoff at our phones all you like, these delicate extensions of our fingers, but know that through this technology that you couldn’t even begin to understand, we have smudged the entire world with our fingerprints. We are the generation of knowledge, and we are learning more than any that came before us. So, frown at my typing fingers; I am using them to grasp power by the throat. Try to invalidate us, but we’ve heard our parents talking about the world’s crashing and burning since we had sprung from the womb. We know you’ve fucked up, and we’re angry about it- the kind of anger that fuels knowledge, that I feel in my veins every time I read the news from my phone before school, that sticks in my throat like honey in a debate; the kind of anger that simmers, that sharpens teeth into daggers, that makes this generation more dangerous than you could have ever imagined. We are the generation of change, and goddammit, we’re coming.

Research from the Life and Health Sciences Research Institute in Portugal suggests a possible explanation: sustained stress causes us to fall back on familiar routines. The part of our brain associated with decision-making and goal-directed behaviors shrinks and the brain regions associated with habit formation grow when we’re under chronic stress.

An influx of new research explores how our brains do continue to change and how our very thoughts impact those changes. This natural tendency of our brains to rewire is called neuroplasticity, which can be influenced by both external and internal factors.

the brain is most effective at learning new material when stress hormones are slightly elevated by a novel experience, a theory verified by modern brain imaging. Therefore, the best way to rethink something we’ve been doing for years—the way we do our jobs, the way we interact with others, the way we see the world—is to step outside of ourselves, and outside of our comfort zone.

Last Night’s Moon," “When will we next walk together under last night’s moon?” - Tu Fu March aspens, mist forest. Green rain pins down the sea, early evening cyanotype. Silver saltlines, weedy toques of low tide, pillow lava’s black spill indelible in the sand. Unbroken broken sea. — Rain sharpens marsh-hair birth-green of the spring firs. In the bog where the dead never disappear, where river birch drown, the surface strewn with reflection. This is the acid-soaked moss that eats bones, keeps flesh; the fermented ground where time stops and doesn’t; dissolves the skull, preserves the brain, wrinkled pearl in black mud. — In the autumn that made love necessary, we stood in rubber boots on the sphagnum raft and learned love is soil–stronger than peat or sea– melting what it holds. The past is not our own. Mole’s ribbon of earth, termite house, soaked sponge. It rises, keloids of rain on wood; spreads, milkweed galaxy, broken pod scattering the debris of attention. Where you are while your body is here, remembering in the cold spring afternoon. The past is a long bone. — Time is like the painter’s lie, no line around apple or along thigh, though the apple aches to its sweet edge, strains to its skin, the seam of density. Invisible line closest to touch. Lines of wet grass on my arm, your tongue’s wet line across my back. All the history in the bone-embedded hills of your body. Everything your mouth remembers. Your hands manipullate in the darkness, silver bromide of desire darkening skin with light. — Disoriented at great depths, confused by the noise of shipping routes, whales hover, small eyes squinting as they consult the magnetic map of the ocean floor. They strain, a thousand miles through cold channels; clicking thrums of distant loneliness bounce off seamounts and abyssal plains. They look up from perpetual dusk to rods of sunlight, a solar forest at the surface. Transfixed in the dark summer kitchen: feet bare on humid linoleum, cilia listening. Feral as the infrared aura of the snake’s prey, the bees’ pointillism, the infrasonic hum of the desert heard by the birds. The nighthawk spans the ceiling; swoops. Hot kitchen air vibrates. I look up to the pattern of stars under its wings.

Power makes us smarter, more ambitious, more aggressive and more focused. These qualities are sharpened when we win, and they boost our chances of winning in the future. Power changes us in such a way that it opens doors in our brain that help us gain more power. Power, in other words, empowers us to be winners through a positive feedback loop, a virtuous cycle of power-induced brain changes that make us even more of a winner in the future.

The other major hormonal player in your cycle is progesterone. It helps to prepare the uterus for implantation with a healthy fertilized egg and supports pregnancy. If no implantation occurs, progesterone levels drop, and another cycle begins. Progesterone receptors are highly concentrated in the brain. Progesterone can support GABA, the brain’s relaxation neurotransmitter; acts to protect your nerve cells; and supports the myelin sheath that covers neurons. I like to think of progesterone as the “feel-good hormone.” It makes you feel calm and peaceful and encourages sleep. It’s like nature’s Valium, but better, because instead of making your brain fuzzy, it sharpens your thinking. It has also been shown to help with brain injuries by reducing inflammation and counteracting damage. It is so much more than a sex hormone. Progesterone increases during pregnancy, which is why many pregnant women often feel great. Some women with hormonal issues, in fact, feel so much better during pregnancy that they will

An apt analogy for how the brain consolidates new learning may be the experience of composing an essay. The first draft is rangy, imprecise. You discover what you want to say by trying to write it. After a couple of revisions you have sharpened the piece and cut away some of the extraneous points. You put it aside to let it ferment. When you pick it up again a day or two later, what you want to say has become clearer in your mind. Perhaps you now perceive that there are three main points you are making. You connect them to examples and supporting information familiar to your audience. You rearrange and draw together the elements of your argument to make it more effective and elegant.

Bringing incredible creative projects to life demands much hard work down in the trenches of day-to-day idea execution. Genius truly is “1 percent inspiration and 99 percent perspiration.” But we cannot forget the flip side of that 99 percent—it’s impossible to solve every problem by sheer force of will. We must also make time for play, relaxation, and exploration, the essential ingredients of the creative insights that help us evolve existing ideas and set new projects in motion. Often this means creating a routine for breaking from your routine, working on exploratory side projects just for the hell of it, or finding new ways to hotwire your brain’s perspective on a problem. It also means learning how to put your inner critic on mute, banish perfectionist tendencies, and push through anxiety-inducing creative blocks. To stay creatively fit, we must keep our minds engaged and on the move—because the greatest enemy of creativity is nothing more than standing still.

Unnecessary Creation gives you the freedom to explore new possibilities and follow impractical curiosities. Some of the most frustrated creative pros I’ve encountered are those who expect their day job to allow them to fully express their creativity and satisfy their curiosity. They push against the boundaries set by their manager or client and fret continuously that their best work never finds its way into the end product because of restrictions and compromises. A 2012 survey sponsored by Adobe revealed that nearly 75 percent of workers in the United States, United Kingdom, Germany, France, and Japan felt they weren’t living up to their creative potential. (In the United States, the number was closer to 82 percent!) Obviously, there’s a gap between what many creatives actually do each day and what they feel they are capable of doing given more resources or less bureaucracy. But those limitations aren’t likely to change in the context of an organization, where there is little tolerance for risk and resources are scarcer than ever. If day-to-day project work is the only work that you are engaging in, it follows that you’re going to get frustrated. To break the cycle, keep a running list of projects you’d like to attempt in your spare time, and set aside a specific time each week (or each day) to make progress on that list. Sometimes this feels very inefficient in the moment, especially when there are so many other urgent priorities screaming for your attention, but it can be a key part of keeping your creative energy flowing for your day-to-day work. You’ll also want to get a notebook to record questions that you’d like to pursue, ideas that you have, or experiments that you’d like to try. Then you can use your pre-defined Unnecessary Creation time to play with these ideas. As Steven Johnson explains in his book Where Good Ideas Come From, “A good idea is a network. A specific constellation of neurons—thousands of them—fire in sync with each other for the first time in your brain, and an idea pops into your consciousness. A new idea is a network of cells exploring the adjacent possible of connections that they can make in your mind.”18

COUNT. What’s to stop you taking her with you to London? FIGARO. A man who was married and had to be away so much? I’d never hear the end of it. COUNT. But with your qualities and brains you could climb the ladder and end up with an important government post one of these days. FIGARO. Brains? Climb the ladder? Your Lordship must think I’m stupid. Second-rate and grovelling, that’s the thing to be, and then the world’s your oyster. COUNT. All you’d have to do is take a few lessons in politics from me. FIGARO. I know what politics is. COUNT. Like you know the key to the English language? FIGARO. Not that it’s anything to boast about. It means pretending you don’t know what you do know and knowing what you don’t, listening to what you don’t understand and not hearing what you do, and especially, claiming you can do more than you have the ability to deliver. More often that not, it means making a great secret of the fact that there are no secrets; locking yourself in your inner sanctum where you sharpen pens and give the impression of being profound and wise, whereas you are, as they say, hollow and shallow; playing a role well or badly; sending spies everywhere and rewarding the traitors; tampering with seals, intercepting letters, and trying to dignify your sordid means by stressing your glorious ends. That’s all there is to politics, and you can have me shot if it’s not. COUNT. But what you’ve defined is intrigue. FIGARO. Call it politics, intrigue, whatever you want. But since to me the two things are as alike as peas in a pod, I say good luck to whoever has anything to do with either. ‘Truly, I love my sweetheart more’, as old King Henry’s song goes.

As it happened, the child’s mother was a radiologist. The tumor looked malignant—the mother had already studied the scans, and now she sat in a plastic chair, under fluorescent light, devastated. “Now, Claire,” the surgeon began, softly. “Is it as bad as it looks?” the mother interrupted. “Do you think it’s cancer?” “I don’t know. What I do know—and I know you know these things, too—is that your life is about to—it already has changed. This is going to be a long haul, you understand? You have got to be there for each other, but you also have to get your rest when you need it. This kind of illness can either bring you together, or it can tear you apart. Now more than ever, you have to be there for each other. I don’t want either of you staying up all night at the bedside or never leaving the hospital. Okay?” He went on to describe the planned operation, the likely outcomes and possibilities, what decisions needed to be made now, what decisions they should start thinking about but didn’t need to decide on immediately, and what sorts of decisions they should not worry about at all yet. By the end of the conversation, the family was not at ease, but they seemed able to face the future. I had watched the parents’ faces—at first wan, dull, almost otherworldly—sharpen and focus. And as I sat there, I realized that the questions intersecting life, death, and meaning, questions that all people face at some point, usually arise in a medical context. In the actual situations where one encounters these questions, it becomes a necessarily philosophical and biological exercise. Humans are organisms, subject to physical laws, including, alas, the one that says entropy always increases. Diseases are molecules misbehaving; the basic requirement of life is metabolism, and death its cessation. While all doctors treat diseases, neurosurgeons work in the crucible of identity: every operation on the brain is, by necessity, a manipulation of the substance of our selves, and every conversation with a patient undergoing brain surgery cannot help but confront this fact. In addition, to the patient and family, the brain surgery is

10 Practical Strategies to Improve Your Critical Thinking Skills and Unleash Your Creativity In today's rapidly changing world, the ability to think critically and creatively has become more important than ever. Whether you're a student looking to excel academically, a professional striving for success in your career, or simply someone who wants to navigate life's challenges with confidence, developing strong critical thinking skills is crucial. In this blog post, we will explore ten practical strategies to help you improve your critical thinking abilities and unleash your creative potential. 1. Embrace open-mindedness: One of the cornerstones of critical thinking is being open to different viewpoints and perspectives. Cultivate a willingness to listen to others, consider alternative opinions, and challenge your own beliefs. This practice expands your thinking and encourages creative problem-solving. 2. Ask thought-provoking questions: Asking insightful questions is a powerful way to stimulate critical thinking. By questioning assumptions, seeking clarity, and exploring deeper meanings, you can uncover new insights and perspectives. Challenge yourself to ask thought-provoking questions regularly. 3. Practice active listening: Listening actively involves not just hearing, but also understanding, interpreting, and empathizing with the speaker. By honing your active listening skills, you can better grasp complex ideas, identify underlying assumptions, and engage in more meaningful discussions. 4. Seek diverse sources of information: Expand your knowledge base by seeking information from a wide range of sources. Engage with diverse perspectives, opinions, and ideas through books, articles, podcasts, and documentaries. This habit broadens your understanding and encourages critical thinking by exposing you to different viewpoints. 5. Develop analytical thinking skills: Analytical thinking involves breaking down complex problems into smaller components, examining relationships and patterns, and drawing logical conclusions. Enhance your analytical skills by practicing activities like puzzles, riddles, and brain teasers. This will sharpen your ability to analyze information and think critically. 6. Foster a growth mindset: A growth mindset is the belief that your abilities can be developed through dedication and hard work. Embracing this mindset encourages you to view challenges as opportunities for growth, rather than obstacles. By persisting through difficulties, you build resilience and enhance your critical thinking abilities. 7. Engage in collaborative problem-solving: Collaborating with others on problem-solving tasks can spark creativity and strengthen critical thinking skills. Seek out group projects, brainstorming sessions, or online forums where you can exchange ideas, challenge each other's thinking, and find innovative solutions together. 8. Practice reflective thinking: Taking time to reflect on your thoughts, actions, and experiences allows you to gain deeper insights and learn from past mistakes. Regularly engage in activities like journaling, meditation, or self-reflection exercises to develop your reflective thinking skills. This practice enhances your critical thinking abilities by promoting self-awareness and self-improvement. 9. Encourage creativity through experimentation: Creativity and critical thinking often go hand in hand. Give yourself permission to experiment and explore new ideas without fear of failure. Embrace a "what if" mindset and push the boundaries of your thinking. This willingness to take risks and think outside the box can lead to breakthroughs in critical thinking. 10. Continuously learn and adapt: Critical thinking is a skill that can be honed throughout your life. Commit to lifelong learning and seek opportunities to expand your knowledge and skills. Stay curious, be open to new experiences, and embrace change.

Could it be that the cannabinoid network is precisely the sort of adaptation that natural selection would favor in the evolution of a creature who survives by hunting? A brain chemical that sharpens the senses, narrows your mental focus, allows you to forget everything extraneous to the task at hand (including physical discomfort and the passage of time), and makes you hungry would seem to be the perfect pharmacological tool for man the hunter. All at once it provides the motive, the reward, and the optimal mind-set for hunting.

When it comes to your nutrition, you are what you eat. When it comes to your fitness, you are how you move. Movement shapes your muscles, strengthens your heart and lungs, sharpens your brain and elevates your mood. When you’ve exerted yourself all day – I mean, worked really, really hard, nothing feels better than relaxing afterwards, when you’ve earned that rest. When you spend all day running around, and then you sink into a comfortable couch, you feel like you’re on a cloud. But when you’ve done nothing but sit around all day, you feel terrible, don’t you? It’s like your body is made of lead.

The challenge is that the demand in our lives increasingly exceeds our capacity. Think of capacity as the fuel that makes it possible to bring your skill and talent fully to life. Most of us take our capacity for granted, because for most of our lives we’ve had enough. What’s changed is that between digital technology and rising complexity, there’s more information and more requests coming at us, faster and more relentlessly than ever. Unlike computers, however, human beings aren’t meant to operate continuously, at high speeds, for long periods of time. Rather, we’re designed to move rhythmically between spending and renewing our energy. Our brains wave between high and low electrical frequencies. Our hearts beat at varying intervals. Our lungs expand and contract depending on demand. It’s not sufficient to be good at inhaling. Indeed, the more deeply you exhale, the calmer and more capable you become. Instead, we live linear lives, progressively burning down our energy reservoirs throughout the day. It’s the equivalent of withdrawing funds from a bank account without ever making a deposit. At some point, you go bankrupt. The good news is that we can influence the way we manage our energy. By doing so skillfully, you can get more done in less time, at a higher level of quality, in a more sustainable way. A couple of key scientific findings point the way. The first is that sleep is more important than food. You can go a week without eating and the only thing you’ll lose is weight. Give up sleep for even a couple of days and you’ll become completely dysfunctional. Even so, we’re all too willing to trade away an hour of sleep in the false belief that it will give us one more hour of productivity. In fact, even very small amounts of sleep deprivation take a significant toll on our cognitive capacity. The notion that some of us can perform adequately with very little sleep is largely a myth. Less than 2.5 percent of the population—that’s one in forty people—feels fully rested with less than seven to eight hours of sleep a night. The second key finding is that our bodies follow what are known as ultradian

Here’s the thing about close combat in real life: It’s almost always over in a matter of seconds. Not like in the movies, where your hero has the luxury to strategize and maneuver and grapple for minutes on end. Fortunately, when your life is in danger, your brain kicks in. Deep inside your brain this little almond-shaped gland called the amygdala sends out the signal to make your body start pumping out dopamine and adrenaline and cortisol. Time seems to slow, your focus sharpens, you suddenly start perceiving way more stimuli than normal. Neurologists call this tachypsychia. Everyone else calls it the fight-or-flight response. Cavemen who didn’t have it got eaten by saber-toothed tigers. So I made a quick decision. I could either be incapacitated by a Taser, or I could put myself within the reach of Bondarchuk’s fists. No choice.

By developing a habit of telling ourselves stories about what’s going on around us, we learn to sharpen where our attention goes. These storytelling moments can be as small as trying to envision a coming meeting while driving to work—forcing yourself to imagine how the meeting will start, what points you will raise if the boss asks for comments, what objections your coworkers are likely to bring up—or they can be as big as a nurse telling herself stories about what infants ought to look like as she walks through a NICU. If you want to make yourself more sensitive to the small details in your work, cultivate a habit of imagining, as specifically as possible, what you expect to see and do when you get to your desk. Then you’ll be prone to notice the tiny ways in which real life deviates from the narrative inside your head. If you want to become better at listening to your children, tell yourself stories about what they said to you at dinnertime last night. Narrate your life, as you are living it, and you’ll encode those experiences deeper in your brain. If you need to improve your focus and learn to avoid distractions, take a moment to visualize, with as much detail as possible, what you are about to do. It is easier to know what’s ahead when there’s a well-rounded script inside your head.

Neuroplasticity simply means that the brain is capable of being molded: it can change and develop more connections between its many nerve cells so that, to a degree, it can even develop more cells. Neurogenesis is a similar term; it means that the brain is capable of growth and development.

Norepinephrine: The Wake-Up Neurotransmitter One of norepinephrine’s effects on the brain is to sharpen attention. As we saw earlier, norepinephrine (aka noradrenaline) can function as both a neurotransmitter and a hormone. When we perceive stress and activate the fight-or-flight response, the brain produces bursts of norepinephrine, triggering anxiety. But sustained and moderate secretion can also produce a beneficial result in the form of heightened attention, even euphoria, and meditation has been shown to produce a rise in norepinephrine in the brain. A modest dose of norepinephrine is also associated with reduced beta brain waves. 5.11. Norepinephrine: your wake-up molecule. Notice the paradox here. Norepinephrine is associated with both anxiety and attentiveness. How do you get enough to be alert, but not so much you’re stressed? Surrender is the key. Steven Kotler, co-author of Stealing Fire, says that stress neurochemicals like norepinephrine actually prime the brain for flow states. At first, the meditator is frustrated by Monkey Mind. But if she surrenders, despite the perpetual self-chatter of the DMN, she enters the next phase of flow, which is focus. She has hacked her biology, using the negative experience of mind wandering as a springboard to flow. Norepinephrine’s molecular structure is similar to its cousin, epinephrine. While epinephrine works on a number of sites in the body, norepinephrine works exclusively on the arteries. When both dopamine and norepinephrine are present in the brain at the same time, they amplify focus. Attention becomes sharp, while perception is enhanced. Staying alert is a key function of the brain’s attention circuit, which keeps you focused on the object of your meditation and counteracts the wandering mind. It also stops you from becoming drowsy, an occupational hazard for meditators. That’s because pleasure neurotransmitters such as serotonin and melatonin (for which serotonin is the precursor) can put you to sleep if not balanced by alertness-producing norepinephrine. Again, the ratios are the key. Oxytocin: The Hug Drug 5.12. Oxytocin: your cuddle molecule. Oxytocin is produced by the hypothalamus, part of the brain’s limbic system. When activated, neurons in the hypothalamus stimulate the pituitary gland to release oxytocin into the bloodstream. So even though oxytocin is produced in the brain, it has effects on the body as well, giving it the status of a hormone. It is one of a group of small protein molecules called neuropeptides. A closely related neuropeptide is vasopressin. All mammals produce some variant of these neuropeptides. Oxytocin promotes bonding between humans. It is responsible for maternal feelings and physically prepares the female body for childbirth and nursing. It is generated through physical touch but also by emotional intimacy. Oxytocin also facilitates generosity and trust within a group. Oxytocin is the hormone associated with the long slow waves of delta. A researcher hooking subjects up to an EEG found that touch stimulated greater amounts of delta, with certain regions of the skin being more sensitive. The biggest effect was produced by tapping the cheek, as we do in EFT. It produced an 800% spike in delta.
