Boxing brought me money and fame, but it never brought me no happiness.

I don’t react to a tragic happening any more. I took so many bad things as a kid and some people think I don’t care about anything. It’s just too hard for me to get emotional. I can’t cry no more.

I’m a dreamer. I have to dream and reach for the stars, and if I miss a star then I grab a handful of clouds.
