Don’t stop when you are tired. Stop when you are done. - David Goggins

From then on, I brainwashed myself into craving discomfort. If it was raining, I would go run. Whenever it started snowing, my mind would say, Get your fucking running shoes on. Sometimes I wussed out and had to deal with it at the Accountability Mirror. But facing that mirror, facing myself, motivated me to fight through uncomfortable experiences, and, as a result, I became tougher. And being tough and resilient helped me meet my goals.

Then I thought of an English middle-distance runner from back in the day named Roger Bannister. When Bannister was trying to break the four-minute mile in the 1950s, experts told him it couldn’t be done, but that didn’t stop him. He failed again and again, but he persevered, and when he ran his historic mile in 3:59.4 on May 6, 1954, he didn’t just break a record, he broke open the floodgates simply by proving it possible. Six weeks later, his record was eclipsed, and by now over 1,000 runners have done what was once thought to be beyond human capability.

Every minute you spend feeling sorry for yourself is another minute not getting better, another morning you miss at the gym, another evening wasted without studying. Another day burned when you didn’t make any progress toward your dreams, ambitions, and deepest desires. The ones you’ve had in your head and heart your entire life.
