You have to compete in life because if you don't have no competition - no competition, no spirit, you know, you'll fall under the slightest struggle.

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.

I'm not used to sensitivity any more. When I see people cry when I lose, save your tears. I don't know how to handle people crying any more. I lost my sensitivity like that. Please, you embarrass me when you cry because I don't know what to do when you cry. I don't know what to say.

Boxing is an ego-driven sport. The idea is to not get too personal or emotional with it. You just know when it's over, it's over, and that's it.

I am the most ruthless, brutal champion ever. There is no one who can match me. I want your heart. I want to eat your children.

I'm the most brutal and ruthless conquerer there has ever been.

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.
