David Goggins is a force of nature. Aside from the lessons that I draw from Mother Nature herself, I know of no other motivating force that is as powerful and effective as David Goggins. Mr. Goggins doesn't write about natural law as I do, but he is living proof of their existence. Natural Law 101 is all about self-mastery. There is no one alive who has worked harder, through physical exertion to improve his mind and body than David Goggins. We were born with a special dispensation to reason and apply logic to reach common sense conclusions - we have also been given higher gifts of optimism and energy, focus, foresight, and insight. But these gifts were meant to be cultivated and nourished. If we don’t use our gifts, we lose our gifts. If that happens, bad things happen to us and our society. David Goggins makes the connection between self-mastery and societal good. He sums up stoic philosophy by example. His physical endurance, work ethic, and tolerance to pain, boggle the brain and make us ask what might we be leaving in the tank. To read about his physical challenges, hell weeks (3 in one year to become a Navy seal) ultra marathons of over 136 miles in 24 hours, 4000 pull-ups in 19 hours (a world record) you don’t think any human being is capable of enduring such pain - But he does.
