Books about successful people often make success sound rather unappealing. Education should be intense and rigorous, focused on driving up IQ and on the ‘STEM’ quaternity of science, technology, engineering, and mathematics. Once adulthood is reached, life follows an austere pattern, with a 5am start, cold baths, daily visits to the gym, little or no alcohol, a Huel-rich diet, and Stakhanovite working hours. This last point generates particular excitement, and descriptions of powerful people dwell with eager fascination on how many hours they devote to their labors.
