Childhood was a nightmare for David Goggins, with poverty, bigotry, and physical abuse colouring his days and haunting his nights. Goggins went from a despondent, overweight young man with no future to a US Armed Forces icon and one of the world’s best endurance athletes through self-discipline, mental tenacity, and hard effort. He was the only man in history to finish elite training as a Navy SEAL, Army Ranger, and Air Force Tactical Air Controller, and he went on to establish records in a variety of endurance contests, earning him the title of The Fittest (Real) Man in America from Outside magazine.
