Modern neuroscience teaches us that the path to courage and success lies through accepting pain and fear, and not through their avoidance. If ever there was a real-life example of this, it is the story of David Goggins. Goggins has learned to harness the elusive holy grail of human existence: the ability to rewire one's brain to constantly achieve more and become better, regardless of feelings, external conditions or motivational state.

David Goggins' childhood was a nightmare - poverty, prejudice and physical violence. But through self-discipline, mental toughness, and hard work, Goggins transformed himself from an overweight depressed youth with no future into an icon of the U.S. Armed Forces and one of the world's best endurance athletes.

In the book, he talks about how most of us only use 40% of our capabilities. Goggins calls it the "40% rule," and his story illuminates a path anyone can take to overcome pain, eliminate fear, and reach their full potential.

David Goggins is a retired Navy SEAL and the only member of the U.S. Armed Forces to complete Navy SEAL training, U.S. Army Ranger School, and Air Force Tactical Air Controller training. Goggins has competed in over sixty ultramarathons, triathlons and ultratriathlons, setting new course records and regularly placing in the top five.
