We have called this state the flow experience, because this is the term many of the people we interviewed had used in their descriptions of how it felt to be in top form: “It was like floating,” “I was carried on by the flow.” It is the opposite of psychic entropy—in fact, it is sometimes called negentropy—and those who attain it develop a stronger, more confident self, because more of their psychic energy has been invested successfully in goals they themselves had chosen to pursue.
