I would love to fight Brock Lesnar. He's a massive dude.

Even though I have bad qualities in my personal life, as an athlete, I can turn it on.

It was really tough being in jail. It doesn't get much lower. You're in a filthy room. The food is terrible, and you're surrounded by people who have done all types of crazy crimes. You have nothing that belongs to you, not even your own underwear. It's just terrible.

I got in the limelight at a young age. At age 19, people were already comparing me to Anderson Silva.

I was never popular. I always kind of wanted to be accepted with the rich kids, with the cool kids, and I never had that.

Growing up, I was poor. In college, I was poor. I never had anything.

College, for me, was more about wrestling than actually going to classes.

My wrestling dream was to become a Division I national champion. That was my No. 1 dream - not Olympics, not money. Just winning that tournament.

I'll see trash talk and people telling me why they're favorite fighter is going to beat me. It motivates me for sure.

The biggest challenge is learning how to psych yourself up into believing in yourself as you walk into the Octagon.
