Dan Koe's April 23, 2022 video lists seven life-changing books—Tolle's The Power of Now/A New Earth, Deida, The Kybalion, Watts, de Mello, Kotler, and Csikszentmihalyi—framing them as spiritual/philosophical primers that improve self-awareness and peak performance. He emphasizes Kotler's five flow drivers (curiosity, passion, purpose, autonomy, mastery) and Csikszentmihalyi's flow ideas including 'psychic entropy' and numerical information-processing claims.
