MIHALY CSIKSZENTMIHALYI (1934-2021) (pronounced "chick-SENT-me high") was a Hungarian-born polymath who recognized and named the psychological concept of "flow," a highly focused mental state conducive to productivity. He was Distinguished Professor of Management at Claremont Graduate University and the former head of the Department of Psychology at the University of Chicago and of the Department of Sociology and Anthropology at Lake Forest College. His research and theories in the psychology of optimal experience have revolutionized psychology and have been adopted in practice by national leaders such as Bill Clinton and Tony Blair as well as top members of the global executive elite who run the world's major corporations. Csikszentmihalyi is the author of several popular books about his theories, including the bestselling Flow: The Psychology of Optimal Experience; The Evolving Self: A Psychology for The Third Millennium; Creativity; and Finding Flow. The Wall Street Journal has listed Flow among the six books "every well-stocked business library should have." The Conversation: https://www.edge.org/conversation/mihaly_csikszentmihalyi-flow
