It's kind of a weird thing when you've been at the top of a division you've been in your entire career to kind of take a backseat because of friendship.

We all go through things in life. You try to stay positive, but you can't ignore bad things that happen. You just try to work through them.

This is a mean world, and everyone likes to jump in and kick people when they're down.

There's guys who train hard. There's guys who believe they're real tough. But there's only a certain amount of guys who believe - like, really believe - they should be the champion. I know I have that mentality, and I know other guys who have that mentality.

The most important thing in a fighter is his mentality. Do you really believe that you're the baddest dude on the planet?

When you're at world championship level, you're fighting other guys who are at a world championship level.
