Flow starts when we say yes to the fight. - Steven Kotler

When free from the confines of our normal identity, we are able to look at life, and the often repetitive stories we tell about it, with fresh eyes. Come Monday morning, we may still clamber back into the monkey suits of our everyday roles — parent, spouse, employee, boss, neighbor — but, by then, we know they're just costumes with zippers.

The point at which someone goes into REM is a fantastic indicator of depressive tendencies,” said Britton. “We’ve gotten very good at this kind of research. If you took 100 people and did a sleep study, we can look at the data and know, by looking at the time they entered REM, who’s going to become depressed in the next year and who isn’t.” Normal people enter REM at 90 minutes. Depressed people enter at 60 minutes or sooner. It works the same in the other direction. Happy people go into REM around 100 minutes. Britton found that the vast majority of her near-death group entered REM sleep at 110 minutes — a rating that is nearly off-the-charts for overall life-satisfaction and a neurophysiological correlate that supports the anecdotal evidence that these strange states are literally and completely transformative.

Curiosity into passion; passion into purpose; and purpose into patient profit — that’s the safest way to play this game.
