I went through a change in my life and my career where I finally understood how to train and prepare. I finally understood what it meant, and I've had so many fantasies about being able to go back and be 16 again. And redo parts of my high school career. Redo all of my college career. Redo my attempt to make an Olympic team.

You've got to listen to your body, notice some trends in yourself and do the best you can to be ready when a finish line approaches.

You're looking at the reflection of perfection. You're looking at the man who gets all your attention. You're looking at the man with the biggest arm. At the man, with the greatest charm, the man in Chicago who will do harm to the guy three doors down. Whatcha gonna do, when you know who? How ya gonna deal, with the man of steel? How ya gonna react to Sonnen's attack?

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.

When I was young they used to call me 'The Foreman,' not because I was in charge but because I did the work of four men.

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.
