Mihaly Csikszentmihalyi discovered that people find genuine satisfaction during a state of consciousness called Flow. In this state they are completely absorbed in an activity, especially an activity which involves their creative abilities. During this “optimal experience” they feel “strong, alert, in effortless control, unselfconscious, and at the peak of their abilities.” In the footsteps of Maslow, Csikszentmihalyi insists that happiness does not simply happen. It must be prepared for and cultivated by each person, by setting challenges that are neither too demanding nor too simple for ones abilities.
