I think a trainer is very important at the beginning of a fighter's career. A fighter needs to know how to throw a left, throw a right, how to duck, how to do certain things. Over time, you don't really need a trainer. You've got to train yourself. You've got to motivate yourself. And I don't think anybody can put that in you.

When Don King's fighters lose their titles they come back fighting on the undercard for peanuts. King owns all the top heavyweights and we spar against each other but we get charged for it and that comes out of our purses.

I think the world is changing. And it's changing so fast that people have to change with it.

Don King was good to me through my years as champion, but I wouldn't trust him as far as I could throw him. He's a wheeler dealer and you've got to be careful. He's a great con artist.

Tyson is a lot better than I thought, a lot better. People can talk about Spinks all they want... Tyson is the true champion.

I train myself. I don't have trainers who want hundreds of thousands of dollars to train me. I hire who I want to put the grease on my face, to rub my neck and rub my back, to take my mouthpiece out and rinse it off and put the mouthpiece back in. And then I go about my business. And if they want to say something, they can give me little reminders. All you need are reminders. You don't need 'big-time' trainers.

Ali was a guy that had a lot of discipline. If you hung around him, you'd be able to get some of that discipline that he had. And I learned from that. He was a sweet man.
