I throw so hard because I sit and wait for that perfect moment.

Basically, I guess they just thinking I've been winning my fights just by luck. I just think I've been winning my fights on heart.

I used to only train 30 minutes a day.

It's all the stuff I've been through in my life. From family struggles, people doubting me, things I went through as a child and going to prison, they all played a factor in who I am today. It really made me a better person. Going through those situations can make or break you as a human being.

I've been having people doubt me all my life.

In 2010, Strikeforce came to Houston, and DC was something like 5-0 or 6-0, and I'd seen him at the expo. I seen him walking around and I seen he had a pink cast on his hand, and I was like, this guy is way too fat... because he looked shorter and fatter. Because back then I was slim, I was like 235. So, I was like, man, I could take this guy.

You've got to try to find some type of mental edge on your opponent.

It's like I say all the time, it's the heavyweight division. It doesn't matter if the guys a black belt or if he's a world-class boxer. We still have a 50-50 chance.

I have a lot of anger built up in me from my childhood. My wife and kids are the only ones who give me peace in this world.
