I started to shortcircuit because I had high aspirations for the film. I never told anybody that.

I started having some memory-loss issues. I took a neurological exam, and they said, "Well, you should stop fighting now." And I kept begging them for one more fight, one more fight, and the doctor said to me, "How much are they going to pay you?" I was supposed to fight three more times, and one would have been for a cruiser belt. So I said, "I just need to fight three more times." He said, "Listen, you can't even get hit in the head one more time, your neuro is so bad."

My dogs are more important than my family.

I come from a violent background. So I became hard. I realised that I had made myself that way to deal with a feeling of abandonment and shame.

I get a call, and it's Howard Bingham, and he's got the champ on the line.Muhammad Ali didn't remember me from being a kid, but he was going, "Yeah, you're in bed, and you want your mama with you . . ." It really helped so much. He spent 15 or 20 minutes on the phone with me. That's a memory that I'll always cherish.

Acting was never my first choice as a profession, but I came to terms with it when I decided I better buckle down and be the best I can be at it.

I was very ashamed of seeing a therapist because I thought only crazy people went, and then, after about nine years, I asked him, 'Well, was I really crazy?' And he nodded and said, 'You were but not any more.'
