The four key features that characterize Flow, or what 10000 hours of practice gets you

The first is an intense and focused absorption that makes you lose all sense of time. The second is what is known as autotelicity, the sense that the activity you are engaged in is rewarding for its own sake. The third is finding the "sweet spot", a feeling that your skills are perfectly matched to the task at hand, leaving you neither frustrated nor bored. And finally, flow is characterised by automaticity, the sense that "the piano is playing itself", for example.

Working overtime doesn't increase your output. It makes you stupid.

Which is where sleep comes in. Although we might all like to imagine that we can work happily through the night, once again the data's all against us. Lose just one night's sleep and your cognitive capacity is roughly the same as being over the alcohol limit. Yet we regularly hail as heroes the executives who take the red eye, jump into a rental car, and zoom down the highway to the next meeting. Would we, I wonder, be so impressed if they arrived drunk?

The reason sleep is so important is because fatigue isn't simple. When we are tired, our performance doesn't degrade equally. Instead, when you lose a night's sleep, the parietal and occipital lobes in your brain become less active. The parietal lobe integrates information from the senses and is involved in our knowledge of numbers and manipulation of objects. The occipital lobe is involved in visual processing. So the parts of our mind responsible for understanding the world and the data around us start to slow down. This is because the brain is prioritizing the thalamus—the part of your brain responsible for keeping you awake. In evolutionary terms, this makes sense. If you're driven to find food, you need to stay awake and search, not compare recipes.

Where do good ideas come from? Rejection

The inconsistency of genius is a consistent theme of creativity: Even those blessed with ridiculous talent still produce works of startling mediocrity. (The Beatles are the exception that proves the rule, although their subsequent solo careers prove that even Lennon and McCartney were fallible artists.) The larger point is that mere imagination is not enough, for even those with prodigious gifts must still be able to sort their best from their worst, sifting through the clutter to find what’s actually worthwhile.

Nietzsche stressed this point. As he observed in his 1878 book Human, All Too Human:

Artists have a vested interest in our believing in the flash of revelation, the so-called inspiration … shining down from heavens as a ray of grace. In reality, the imagination of the good artist or thinker produces continuously good, mediocre or bad things, but his judgment, trained and sharpened to a fine point, rejects, selects, connects…. All great artists and thinkers are great workers, indefatigable not only in inventing, but also in rejecting, sifting, transforming, ordering.

Notice the emphasis on rejection. Nietzsche eloquently describes the importance of not just creating but recognizing the value of what has been created.

Your Storytelling Brain

Cognitive Neuroscientist Michael Gazzaniga, a pioneer in the study of hemispheric (left vs. right brain) specialization describes "the Interpreter" - a left hemisphere function that organizes our memories into plausible stories. Less romantic, perhaps, than Gone With the Wind, the Interpreter may help to explain our species' profound relationship with storytelling.
