A lot of people thought you couldn't be a top-level athlete as a vegan, but people like Mac Danzig and Jake Shields are proving that's wrong. And it's better for me as a performer.

People have said to me, 'It must be nice to prove so many people wrong,' but I've never really cared about proving anything to anybody else.

You always have to work to become a better singer, songwriter and performer.

I feel like a lot of fans would like to see me with the heavyweight championship.

In my 20s, it was easy. In your 40s, it's a lot more challenging. You have to look at it like you're an actor, but you're also a professional athlete. You have to train.

Don’t try to prove that anybody is foolish because fools don’t like it. Don’t try to prove to a madman that he is mad, because no madman likes it. He will get angry, arrogant, aggressive. He will kill you if you prove too much. If you come to the point where it can be proved, he will take revenge.

It is better to be foolish yourself, then people enjoy you, and then by a very subtle methodology you can help them change. Then they are not against you.
