It's interesting that you put me in the league with those illustrious fighters [Muhammad Ali, Joe Louis, Jack Johnson], but I've proved since my career I've surpassed them as far my popularity. I'm the biggest fighter in the history of the sport. If you don't believe it, check the cash register.

I earned that the strong will always beat the weak, but the smart will beat the strong. Boxing is a tough guy sport. But in the end, the tough guy gets to clean the streets and be a bodyguard. In the ring, the tough guy is going to get hurt; at the end of the day, he's going to talk funny. Only the smartest win. So, I know it's cliché, but power - real power - comes from knowledge, comes from smarts.

People are going to say what they say. I know sometimes I say things; I offend people.

I know I'm going to blow one day. My life is doomed the way it is. I have no future.

I don't want anyone to have to interview me. I wish I didn't have to talk too much about myself.

Without struggle, there is no progress. There has to be struggle in your life. You have to grow in experience to control your ego. Cause, you know, an ego can be crushed, it can be killed, it can be smashed, but it comes back. It never dies. That's the thing about the ego: it never dies.

I'm trying to figure things out in the world. No one knows what this life thing is all about - there's no manual. Just trying to figure it out.
