From the former heavyweight champion and New York Times bestselling memoirist, an intimate and revealing look at the life and leadership lessons of Cus D Amato, the legendary boxing trainer and Mike Tyson s surrogate father. When legendary boxing trainer Cus D Amato first saw thirteen year old Mike Tyson spar in the ring, he proclaimed, That s the heavyweight champion of the world. D Amato, who had previously managed the careers of Floyd Patterson and Jose Torres, would go on to train the young boxer for several years, and died a few months before Tyson became the youngest heavyweight champion in history. In Tyson s best-selling memoir Undisputed Truth, he recounted the role D Amato played in his formative years, legally adopting him at age sixteen after his mother died and shaping him both physically and mentally after years of living in fear and poverty. Here, Tyson elaborates on the life lessons that D Amato passed down, and reflects on how the trainer s words of wisdom continue to resonate with him outside the ring.
