Can’t Hurt Me

Retired Navy SEAL and ultramarathoner David Goggins tells the brutal story of transforming himself from an overweight, abused kid into one of the toughest endurance athletes alive. Structured as memoir plus challenges, the book argues that most people tap only a fraction of their potential, and lays out his mindset for pushing past pain, fear, and excuses — the “40% rule,” the “accountability mirror,” and callousing the mind. A raw, uncompromising call to master your mind.
