Tupac Shakur always wanted me to smoke weed with him, and I never did it, and I wish I did...That's my biggest regret.

Most writers, in my opinion, are dysfunctional derelicts.

Every win, regardless a good or bad one, gives you more confidence.

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 was an emotional manipulator of fighters . . . You have to know how to be cold, you know? Just have no -emotions, no feelings. It takes time, though, to develop that. I'd been working on that since I was 12 years old. It doesn't happen overnight.

It's interesting that you put me in the league with those illustrious fighters [Muhammad Ali, Joe Louis, Jack Johnson], but I've proved since my career I've surpassed them as far my popularity. I'm the biggest fighter in the history of the sport. If you don't believe it, check the cash register.

I just have this thing inside me that wants to eat and conquer. Maybe it's egotistical, but I have it in me. I don't want to be a tycoon. I just want to conquer people and their souls.
