Lance Armstrong did a number of things, and he gave himself cancer.

Cain Velasquez, for my money, is the most intimidating force ever in heavyweight combat.

There are rules that say 'If a fighter gets old, when a fighter slows down, when a fighter stops looking the same, then he can never come back.' I don't like that.

As fighters, the stark reality is, there's times in that cage when we want out. There's times when we've had enough and we want out, and we're able to recognize defeat.

I go to a wrestling match, and I love it. But at a wrestling match, on every level - that includes Division I - you go into an empty and cold gym, you roll out a mat, and you set 10 chairs up on each side. That's a dual meet, and it's very hard to act like it's a big event.

If your body produces testosterone naturally, fine. Mine doesn't.

I would never discredit the sport or my opponent by reading my injury list before or after the fight. I've always thought it's a very underhanded thing to do, and it's a very cowardly thing to do, to come out and say, 'I'm hurt,' particularly if you win a fight.

The fight takes 15 minutes. The build-up takes 90 days. It takes that for a reason.

My ideal fight would be against the smallest guy with the most atrocious record in the largest venue for the most insane paycheck. I love easy fights.

I'm competitive.

I don't want to be an also-ran.

The greatest form of expression - or, at least, the most common that we have as human beings, what separates us from the animals - is speaking: the ability to communicate.

There's a camaraderie that comes with this sport, but fighting Anderson Silva is a lot like eating Chinese food: twenty minutes after I do it, I'm going to want to do it again.

I have never asked the crowd for their approval, and I will never start.

I don't walk around looking into cameras and telling people I'm the best fighter in the world just to hear myself talk. I say it for the same reason they put warnings on packages of cigarettes, and fighting Chael Sonnen may be hazardous to one's health.

I don't think I've ever had a better experience in the sport than coaching 'The Ultimate Fighter.' I got to do it twice, but I got to really build relationships there that will last forever.

Werdum's open to being knocked out in any fight because he's so reckless, but that's also what makes him so damn dynamic.

There was years when my father didn't even make a hundred grand - or barely made a hundred grand - and sure, we had a maid, but she only came twice a week. What do you think happened the other five days? You think those dishes washed themselves? You think those clothes got themselves in the hamper?

I've been in a position where I've been barely doing any damage, and the ref stopped it. It's just sport.

I like Bryan Caraway a lot; I used to train with him. I consider him a friend.

Brock Lesnar made a career out of refusing to do media and not being accessible.

When I was a kid, I was a big fan of the regional scene. I read 'Pro Wrestling Illustrated,' and I watched Portland Wrestling and everything I could.

I'm a tournament guy; that's what I grew up doing.

Fans don't even know what they want at times.

I had dreams in 2000 of being an Olympian for boxing. I never talk about it.

I've competitively boxed. It's definitely Plan B for me, but I know how to box.

As a fighter, that's not something that ever factors in, whether you go first or last or you walk out first or you walk out second. It's not something that ever factors in or you feel slighted about. I don't think that anybody would care. The job is the same.

Georges St-Pierre is the greatest fighter to have ever done it.

The soreness you feel after a fight or after a good battle, it's the best feeling in the world. You might sit and complain about it, but you feel so accomplished.

Very normal trajectory of a fighter's career - you start out fighting at the YMCA. You move on to the dog park. You get into a coliseum. On your way out, you go back to the YMCA, and then you finish up at the dog park.

The only thing more embellished than Floyd Mayweather's pay-per-view buys is Floyd Mayweather's net worth. But his spending habits are real.

People bring it up to me: 'Well, you're only in your spot because you can talk well.' Okay, first off, you could be right. But second, what - am I supposed to apologize for this? No.

Every time you win, you get another fight. Every time you get a fight, you get promotion, marketing, and media. Those things are what makes stars.

Fighting is an expression. It's a form of speech, and that's why they call it martial arts. It's an art.

One element of wrestling that I know what I grew up with we put a lot of emphasis towards was the takedown. But, you could win an Olympic championship and never score a takedown, and I don't know if MMA fans are even aware of that.

Wrestlers tend to do good in MMA because they tend to be just some tough guys. It's not a karate situation where they grew up their whole life punching the air; in a wrestling situation, you grab a hold of another human being every day.

The kind of wrestler that's going to do well in a combat style event like MMA is one that can explode through - doesn't need to spend time on the mat - hit his opponent, get him off his feet, and get on top quickly.

I'm not going to be one of the guys who hangs around if he doesn't have a road to the title.

I've had a lot of fights, and they haven't all gone my way.

When you go, 'Listen, I didn't know. I didn't know the rules.' That works. That's a good, solid defense. One time.

Whenever you can evoke a strong emotion and want somebody to tune in, whether it's to see you win or get beat up - and I've been on both sides of that - it's a win.

What you don't want is for somebody to not care. Whenever they have no feeling at all, that's bad. Even if they kind of like you or they kind of don't, that's also bad. It's got to be a strong emotion one way or the other.

For me, I prefer to be the heel.

I want to make the UFC money.

The UFC does not owe me a thing. Nothing. I am in debt to them.

I see a lot of people try to come out and copy me, duplicate me, and give it the old college try, but at the end of the day, there's only one Chael Sonnen.

If you call a Brazilian out publicly, you're going to be fighting that Brazilian. That's in their culture.

I'm not after the money or the fame. I'm after the world championship, and that's it.

I'm a wrestler, so I'm used to not being paid, and I'm used to doing five or six competitions a day and paying someone else to allow me into the event.

I train every day but Christmas. I'm not the guy who gets a contract signed and then trains for a fight. I'm at practice every single day, whether I've got a match or not.
