“You know that my refrigerator is never full, and it never will be because I live a mission-driven life, always on the hunt for the next challenge. That mindset is the reason I broke that record, finished Badwater, became a SEAL, rocked Ranger School, and on down the list. In my mind I’m that racehorse always chasing a carrot I’ll never catch, forever trying to prove myself to myself. And when you live that way and attain a goal, success feels anti-climactic.”
