I've achieved 'the American dream.' I feel it's my duty to help others achieve their vision, too - especially the youth.

When I was a boy, I used to pull a big cross saw with my dad. He'd use his right hand, so I'd have to use my left.

Joe Frazier's life didn't start with Ali. I was a Golden Gloves champ. Gold medal in Tokyo '64. Heavyweight champion of the world long before I fought Ali in the Garden.

If I lose, I'll walk away and never feel bad because I did all I could. There was nothing more to do.

I had a job to do in the ring, and the businessmen around me had a job to do outside the ring, I did my job by beating up most of the guys they put in front of me and staying in shape, but the people I trusted didn't do their jobs.

The way I fight, it's not me beatin' the man. I make the man whip himself.

There's one thing I don't ever think about: losing ... Instead, I think about how I'm going to win, and how I can do it the quickest way.
