In his cult book, the outstanding American psychologist of Hungarian origin and former dean of the Faculty of Psychology at the University of Chicago, Mihaly Csikszentmihalyi (born September 29, 1934, in Fiume, Kingdom of Italy—now: Rijeka, Republic of Croatia), presents a completely new approach to the topic of happiness. For him, happiness is akin to inspiration: the state when a person is completely absorbed in an interesting task in which their potential is realized to the maximum, Csikszentmihalyi calls “flow.” The author analyzes this productive state using examples from representatives of the widest range of professions and discovers that the emotional uplift experienced by artists, performers, and musicians is available in any kind of work. Moreover, it needs to be pursued—not only in purposeful activity, but also in relationships, in friendship, in love. The book answers the question of how to learn to do that.
