Can't Hurt Me: The Forty Percent Rule

Let me tell you about a man who should have given up. His name is David Goggins, and his book is called Can't Hurt Me. Fair warning: it's not a gentle book! In his twenties, Goggins weighed nearly three hundred pounds. He worked nights spraying for cockroaches, and he hated his life. He had no confidence, no direction and no plan. One night, he watched a documentary about Navy SEALs. And suddenly, something inside him woke up! But to apply, he had to lose over a hundred pounds in under three months. Everyone told him it was impossible. Everyone! He ran, he swam, and he barely ate. And he actually did it! Later, he survived the SEALs' famous Hell Week, not once, but three times! One of his tools is the Accountability Mirror. He stuck notes on his mirror with brutally honest goals, and he faced them every single morning. No excuses. Have you heard of his forty percent rule? When your mind says you're finished, you've only used about forty percent. There's usually much more left in the tank! He calls this 'callousing your mind'. Look, I'm not saying you should run a hundred miles. But next time you want to quit, wait. Ask yourself, 'Is this really my limit, or just my mind talking?' Then take one more step.
