In numerous studies, Csıkszentmihalyi examined hundreds of “artists, athletes, musicians, chess masters, and surgeons ...people who seemed to spend their time in precisely those activities they preferred” (Csıkszentmihalyi 1991, 4). These studies formed the basis for his theory of“flow”that he developed to describe “optimal experience.” Flow is a psychological state of intense interest, a time when someone becomes fully engaged in a challenging activity that causes them to lose sense of time and self and results in feelings of satisfaction and well-being. In this state,“concentration is so intense that there is no attention left over to think about anything irrelevant, or to worry about problems. Self-consciousness disappears, and the sense of time becomes distorted” (71).
