Freedom is just another word: It seems to get truer the older I get.

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'm becoming more of a novelist as I get older. The novel just seems the truer form. There's less artifice involved.

The most valuable thing to me seems to be time, and with time, I can be great. I have been... and I will be.

Johnny Cash's legacy, I think if it was one word, it would be 'integrity.' He was the original wild man and grew from that guy that was doing all the crazy things that you read that rock n' rollers do to being someone who was like the father of our country, you know. He was a guest at the White House. He was Billy Graham's friend.

I've tried to be more self-sufficient as I've gotten older. I'd like to not worry about whether they're going to sell my next album or book. Hell, William Blake wasn't even published in his lifetime.
