“I trained. I punished myself. I thought making myself suffer on a day-to-day basis would prepare me for climbing hard at high altitude. I slept on the floor. I carried ice in my bare hands. I beat them against the concrete just to see if I could handle it. I never missed an opportunity to train. I ran stairs until I vomited, then ran more.

I ruined relationships to get used to the feeling of failure and sacrifice (it was much easier than holding on). I trained in the gym on an empty diet to learn how far I could push myself without food or water. I imitated and plagiarized the heroes who lived and died before me. I spoke only strong words and ignored weakness at every turn. I subdued my fears. I was opinionated and direct. I became a man either well loved or truly hated. I was ready for anything.”

“Memories and hope are not so different; one is "having done" the other is "to do." Neither constitutes action. You are what you do; thus, if you do nothing, you are nobody. If you once did great things, you think you are great. You coast along on dead, preserved laurels, lifeless and wasting away.”
