'Sunday Morning Coming Down' is probably the most directly autobiographical thing I'd written. In those days, I was living in a slum tenement that was torn down afterwards, but it was $25 a month in a condemned building, and 'Sunday Morning Coming Down' was more or less looking around me and writing about what I was doing.
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.
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.
