Never piss off a gangster.

Listen Wanderlei, I will do a home invasion on you. I will cut the power to your house and the next thing you'll hear is me climbing up your stairs in a pair of night vision goggles I bought in the back of Soldier of Fortune magazine. I'll pick the lock to the master room door, take a picture of you in bed with the Nogueira brothers working on your 'jiu-jitsu'. I'll take said quote unquote photograph, post it at dorksfrombrazil.com, password - not required, username - not required. That, Wanderlei, is how you threaten someone. Dummy.

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.

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.

I hate downtime. I hate it so much. I like to relax like anybody else, but I hate not doing anything. In my life I'm either going full speed or I'm at a stop.

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.

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.
