Csíkszentmihályi hypothesized that people with several very specific personality traits may be better able to achieve flow more often than the average person. These personality traits include curiosity, persistence, low self-centeredness, and a high rate of performing activities for intrinsic reasons only. People with most of these personality traits are said to have an autotelic personality. The term “autotelic” is acquired from two Greek words, auto, meaning self, and telos meaning goal. Being Autotelic means having a self-contained activity, one that is done not with the expectation of some future benefit, but simply to experience it as the main goal.
