If they don't have that extreme addict personality, you can never understand how a guy can blow 300 or 400 million dollars. If I have to live at the top of the world, I also have to live at the bottom of the ocean. I don't know how to live in the middle of life.

My objective is to destroy anybody over 200 pounds, in the ring or out.

I was blessed with speed and a good punch. Everybody thinks I'm the hardest puncher ever. But I just think I was really fast, and my punches got to the target faster. That's what made my knockouts always seem spectacular.

Cus was my father but he was more than a father. You can have a father and what does it mean?—it doesn't really mean anything. Cus was my backbone . . . . He did everything for my best interest . . . . We'd spend all our time together, talk about things that, later on, would come back to me. Like about character, and courage. Like the hero and the coward: that the hero and the coward both feel the same thing, but the hero uses his fear, projects it onto his opponent, while the coward runs. It's the same thing, fear, but it's what you do with it that matters.

I want to rip out his heart and feed it to Lennox Lewis. I want to kill people. I want to rip their stomachs out and eat their children.

Fear is the greatest obstacle to learning. But fear is your best friend. Fear is like fire. If you learn to control it, you let it work for you. If you don’t learn to control it, it’ll destroy you and everything around you. Like a snowball on a hill, you can pick it up and throw it or do anything you want with it before it starts rolling down, but once it rolls down and gets so big, it’ll crush you to death. So one must never allow fear to develop and build up without having control over it, because if you don’t you won’t be able to achieve your objective or save your life.

Confidence applied properly is the path of genius. You must always be in a state of confidence. And the way you sustain a state of confidence is by testing yourself. Difficult quagmires that may occur; there's always a test. You have to seek them out. You constantly have to test yourself to prepare for these quagmires. That's why I always put myself to the test.
