The key to flow is to pursue an activity for its own sake, not for the rewards it brings. - Susan Cain

Today we know that the reality is far more complex. For one thing, the ARAS doesn’t turn stimulation on and off like a fire truck’s hose, flooding the entire brain at once; different parts of the brain are aroused more than others at different times. Also, high arousal levels in the brain don’t always correlate with how aroused we feel. And there are many different kinds of arousal: arousal by loud music is not the same as arousal by mortar fire, which is not the same as arousal by presiding at a meeting; you might be more sensitive to one form of stimulation than to another. It’s also too simple to say that we always seek moderate levels of arousal: excited fans at a soccer game crave hyperstimulation, while people who visit spas for relaxation treatments seek low levels.*

(T)he bittersweet tradition spans centuries—it spans continents. And it teaches us that we are creatures who are born to transform pain into beauty. It also teaches us that our feelings of bittersweetness are some of the greatest gateways that we have to states of creativity and connection and love.

We like to believe that we live in a grand age of creative individualism. We look back at the midcentury era in which the Berkeley researchers conducted their creativity studies, and feel superior. Unlike the starched-shirted conformists of the 1950s, we hang posters of Einstein on our walls, his tongue stuck out iconoclastically. We consume indie music and films, and generate our own online content. We “think different” (even if we got the idea from Apple Computer’s famous ad campaign). But the way we organize many of our most important institutions — our schools and our workplaces — tells a very different story.
