I can't change myself. I'm Mike Tyson. I'm a regular kid from the getto striving to do something positive with myself. I happen to fight well.

Most of my fans are too sensitive. I’m a cruel and cold and hard person. I’ve been abused in every way you can imagine. Save your tears. I lost my sensitivity. You embarrass me when you cry.

I had to persevere because this was my life. This championship, this was the stuff I dreamt of all my life, and I wasn't gonna be denied.

I'm scared every time I go into the ring, but it's how you handle it. What you have to do is plant your feet, bite down on your mouthpiece and say, 'Let's go.'

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

Without discipline, no matter how good you are, you are nothing! One day, and I might not be around; you're going to meet a tough guy who takes your best shot. He'll keep coming because he's tough. Don't get discouraged. That's when the discipline comes in.

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.
