The way to beat the Klitschkos is to get inside, under the jab, and bang to the body. Do that for two or three or four rounds and then the hands will come down and then you turn them over. It's like chopping a tree down. These guys try to headhunt when they fight them and that won't work. But you back them up, the younger brother especially, and he loses heart.

You take that walk from the dressing room to the ring and that's when the real man comes out. Then you climb up those four stairs and into the ring. Then finally, you can't wait for the bell to ring.

[Michael Spinks] didn't belong in the same ring as me, but I wasn't taking good care of myself because of drink and he beat me.

I like the Klitschko boys, I think they're in a class of their own. I like Manny Pacquiao. All the super-middleweights are great.

You have a small period of time when you can perfect your career and become good at it. A lot of guys get distracted, which only hurts them. You must stay focused and work very hard at boxing.

I got messed up between my fight with Ken Norton and my fight with Larry Holmes; I got messed up with alcohol. I needed at least a year more experience, with three or four more fights before I fought Holmes. But I couldn't get any fights. Don King had all the contenders, and unless I signed myself over to him, I couldn't get a fight.

The bad press came because they thought I should fight more. I couldn't get the fights because if I would sign to fight one of King's guys I would be signed to him. I chose not to do that. In hindsight, that might have been a mistake.
