“skilled people can sometimes experience highly enjoyable states (‘flow’ as described by Mihaly Csikszentmihalyi, 1990) during their performance. These states are, however, incompatible with deliberate practice. . . .” Why? Because deliberate practice is carefully planned, and flow is spontaneous. Because deliberate practice requires working where challenges exceed skill, and flow is most commonly experienced when challenge and skill are in balance. And, most important, because deliberate practice is exceptionally effortful, and flow is, by definition, effortless.
