“I still shop at Costco. I just started tipping two years ago.”

Understand that I’m at my best when it comes to proving a point, not only to show that I’m a better fighter and a better athlete at 40½ years old, but I’m at my best when I know I’ve got to beat the system again.

I’m 100 percent clean. I’m doing this off of nuts and bananas.

The only thing I can do is be right about what I say. Because I know I’m being watched. I understand what I’m facing. All I can do is put the work behind it.

I am going in there to win this fight. I don’t think people are taking me seriously. I’m gonna surprise a lot of people. This guy helped two people make history.

I like Sergio Martinez. I think he’s strong, he’s gritty, he’s got plenty of heart, he’s not the fanciest guy you might have seen in boxing but he has the goods to be around a long time in the Middleweight division.

The NBA has a voice that’s why they have a lockout. The NFL has a voice that’s why they had a lockout. Boxing is the only sport that’s individually represented the individual people – Managers, Promoters and Boxers.

The only way you can get experience is from the clock. Time works with some people and against some people. Fortunately, the clock has worked in my favor.

You’re hated by some, loved by others, but that’s what’s great about being different. If everybody loved you, that means you’re not doing the right thing most of the time.

If you don’t know your own value, somebody will tell you your value, and it’ll be less than you’re worth.

Anybody who thinks I’m taking this fight for a paycheck doesn’t know me. My whole life I’ve been achieving the impossible.

I really didn’t care. I’d do something to somebody and walk in front of them the next day like it never happened. I had very very low value on my own life.

I have the philosophy that I’m different. I have the body, the well-being and the experience. Now the teacher gets to show the student that he’s worthy of the lesson. Let me show him through experience.

I’ve done so many unpredictable things and so profoundly. Even the people who want to go against me, are afraid to go against me. They’ve been wrong so many times. A lot of them are just being mum right now. They must feel I can still do things.

I wouldn’t wanna fight me, because I know it wouldn’t be a good outcome for both.

I was told I would be back in 90 days. If I listened to people, I would be back where I came from – the penitentiary.

I’ve got a history of frustrating guys and making them angry.

Motivation is simple. You eliminate those who are not motivated.

Ability is what you’re capable of doing. Motivation determines what you do. Attitude determines how well you do it.

I think sometimes I guess you see records, say you want to get there and use that as motivation. In a way, it’s kind of cool if there is a possibility to rewrite history and be up there with the greats of Olympic history.

I don’t believe in team motivation. I believe in getting a team prepared so it knows it will have the necessary confidence when it steps on a field and be prepared to play a good game.

Vanity is great motivation, to be fair.

There is nothing in art, in philosophy, or in politics to match the fervor of mutual cooperation among discordant bands of fanatics.

And if that’s your sole motivation, it’s going to reflect that narcissistic greed and you’re going to hear it in the music.

Everyone is really afraid of getting out there and not being good. That’s the challenge:
