Ali's belief in himself was something I picked up on, and it's become my own philosophy

It is wonderful. It truly is. It is the only thing that is real! It's you against me, it's challenging another guy's manhood. With gloves. Words cannot describe that feeling of being a man, of being a gladiator, of being a warrior. It's irreplaceable.

You have to know you can win. You have to think you can win. You have to feel you can win.

I've never believed in tying myself up in a long-range contract, and I've been very outspoken on that subject.

I wouldnt change anything because the mistakes and the hurt are as important as all the great fights. They made me who I am today.

Bruce Lee was an artist and, like him, I try to go beyond the fundamentals of my sport. I want the public to see a knockout in the making.

My toughest fight was myself. For me to disclose and let things out was not easy because we don't want to seem weak or like we are different, but I learned that it's okay.
