You should sit in meditation for 20 minutes a day, unless you're too busy, then you should sit for an hour. If Tetris has taught me anything, it's that errors pile up & accomplishments disappear. Everybody has a plan until they get punched in the mouth.

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.

My career has been over since 1990.

I don't have to be that gentleman ["baddest man on the planet"] anymore. Now I have to be "this" guy. And in order to be "this" guy, I have to be smiling, I have to be gregarious, I have to be entertaining, and I have to be friendly. This is what my career needs now. I've adapted. But 20 years from now, I may need a different persona.

When you're a great finisher, you'll become popular. Joe Louis was a great finisher.

I try to catch them right on the tip of his nose, because I try to punch the bone into the brain.

I don't react to a tragic happening any more. I took so many bad things as a kid and some people think I don't care about anything. It's just too hard for me to get emotional. I can't cry no more.
