Direct, blunt, and brutally honest, Grover breaks down what it takes to be unstoppable: you keep going when everyone else is giving up, you thrive under pressure, you never let your emotions make you weak. In "The Relentless 13," he details the essential traits shared by the most intense competitors and achievers in sports, business, and all walks of life. Relentless shows you how to trust your instincts and get in the Zone; how to control and adapt to any situation; how to find your opponent's weakness and attack. Grover gives you the same advice he gives his world-class clients-"don't think"-and shows you that anything is possible. Kobe Bryant raves, "Tim Grover is the master of mental toughness. This book is the blueprint for discovering what you are capable of achieving, getting results you never imagined, reaching the highest level of success-and then going even higher." Relentless is about breaking the rules that hold you back and trusting your instincts to take you where you want to be. Packed with previously untold stories and unparalleled insight into the psyches of the most successful and accomplished athletes of our time, and with all new material for the paperback on achieving excellence in the face of impossible odds, Relentless shows you how even the best get better…and how you can too.
