In boxing, I had a lot of fear. Fear was good. But, for the first time, in the bout with Muhammad Ali, I didn't have any fear. I thought, "This is easy. This is what I've been waiting for". No fear at all. No nervousness. And I lost.

I didn't love school because I wanted to disguise that I was poorer than everybody else. So when I was a teen I reached out in a wrong way. I started to be a mugger, to rob people in the streets, just to supply for my needs.

Forgiveness is that subtle thread that binds both love and friendship. Without forgiveness, you may not even have a child one day.

If you want to be obsessed to be your best, you must get ride of the negative things that are weighing you down.

I was a tiger, a good fighter, in good shape, but I was always nervous before boxing matches.

Today the biggest decisions I make aren't related to the heavyweight title. They are whether I visit McDonalds, Burger King, Wendy's, or Jack-in-the-Box.

Let the other guy have whatever he wants before the fight. Once the bell rings he's gonna be disappointed anyway.
