I don't do camps. Camps are for kids. I don't sleep in tents or roast marshmallows. I certainly don't tell ghost stories or own a sleeping bag. But I do work hard every single day.

If Brock Lesnar was here right now, I'd take my boot off and throw it at him, and he'd better polish it up before he brings it back to me. Talking about he's the baddest guy in the UFC? Brock, quit eating so many raw eggs and doing push-ups because it's affecting your realm of reality. Are you kidding me? I'd slap you in your face, and you wouldn't do anything. 'I'm Brock Lesnar. I've got this $5 haircut and a knife tattooed on my chest.' I'll shove it up your face if you get in Chael Sonnen's way.

My phone rings, they call me up and say, 'Chael, your testosterone level is too high.' I say, 'Well, how high was it?' They say, '0.7.' I said, 'What's normal?' They say, '0.6.'; I said, 'One-tenth? You're telling me I'm one-tenth higher than the average man? Re-test that - you must have caught me on a low day.'

I found that to build mental toughness, you need to inconvenience yourself. The early morning runs, if you hate early mornings. The late night runs, if you hate late nights. The snowy cold, the worst conditions you can get, put yourself in those and really make it inconvenient and you start to get a genuine expectation of winning for the price you have to pay.

As soon as you hear a fighter say, "I'm working smarter, not harder," you always want to bet against that guy. That mentality does not work. You have to work hard. And sometimes that means you are going to work too hard. You are going to decline. You are going to tear down your body and your muscle fibers. You are going to get sick.

Never piss off a gangster.

As soon as you start to get tired, as soon as you start to get behind, as soon as your coach starts yelling at you, a lot of doors open up to quit; you got to find that one reason to stay in that battle, one reason to stay in the fire and fight.
