God lets everything happen for a reason. It's all a learning process, and you have to go from one level to another.

I still can’t believe [ Muhammad Ali ] knows my name. It astounds me he knows who I am. I first met Ali in 1976. I was locked up in a juvenile home and he came to visit. I’ve never forgotten it.

When you see me smash somebody's skull, you enjoy it.

Even though I heard him say he doesn't believe, cuz' that's why from watching Ali gave me the great deal of confidence and deep-down inner belief to believe there's no man fighting that could beat me.

There's no way I would want to hurt him or bust him up. That's why, for the sake of the family as well as himself, I will take him out in the opening round.

I try my best to learn from other people's mistakes. I have a lot of respect for people who can change.

There's nothing wrong with making mistakes, just don't make the same ones. We don't want to duplicate them.
