My only fault is that I don't realize how great I really am.

To be a great champion you must believe you are the best. If you’re not, pretend you are.

I won the Olympic gold medal in Rome, Italy. Olympic champion. The Russian standing right here, and the Pole right here.

Be loud, be pretty and keep their black-hatin' asses in their chairs

I had something to do, which most kids really need. Something they can look forward to - a goal, a purpose to work towards. Something to achieve. Keeps them out of trouble.

I do need publicity but not for what I do for good. I need publicity for my book. I need publicity for my fights. I need publicity for my movie but not for helping people. Then it is no longer sincere.

What I will remember most about Mr Mandela is that he was a man whose heart, soul and spirit could not be contained or restrained by racial and economic injustices, metal bars or the burden of hate and revenge.
