How dare these boxers challenge me with their primitive skills? It makes me angry.

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.

I never look at a high point in my career. Everyone thinks about the Spinks fight, but that fight only lasted 91 seconds, so it's hard to say it defined my career.

I felt the same fear in my first fight as I did in my last fight. It never goes away.

We wanna believe that we're different than the average guy that's working 9-to-5, that our thoughts are different than his. Our inspirations and desires are different than his, that's why we succeed and he didn't cos we wanna believe we're different, but he just didn't get the break that we had...or he wasted it on something else.

Five heads are definitely better than one when they're thinking in the same perspective. I think that you really need to have people that you trust. And for me, trust comes from that synchronizing, that same-mindedness.

People love you when you're successful, but if you're not, who really cares about you?
