Never give up, which is the lesson I learned from boxing. As soon as you learn to never give up, you have to learn the power and wisdom of unconditional surrender, and that one doesn't cancel out the other; they just exist as contradictions. The wisdom of it comes as you get older.
I grew up in a time when people believed in duty, honor and country. My grandfathers were both officers. My father was a General in the Air Force. My brother and I were both in the Army. I've always felt a kinship with soldiers; I think it's possible to support the warrior and be against the war.
I was working the Gulf of Mexico on oil rigs, flying helicopters. I'd lost my family to my years of failing as a songwriter. All I had were bills, child support, and grief. And I was about to get fired for not letting 24 hours go between the throttle and the bottle. It looked like I'd trashed my act. But there was something liberating about it.
