What keeps me going is goals.

My toughest opponent has always been me.

The outgoing and spontaneous person that the world knew while I was boxing was a persona that I created to sell tickets and promote my career. In my private life, I am quiet and reflective by nature.

What you are thinking is what you are becoming.

I'm a Muslim. I've been a Muslim for 20 years. . . . You know me. I'm a boxer. I've been called the greatest. People recognize me for being a boxer and a man of truth. I wouldn't be here representing Islam if it were terrorist. . . . I think all people should know the truth, come to recognize the truth. Islam is peace.

Float like a butterfly, sting like a bee. The hands can't hit what the eyes can't see.

I want to be the first black man on the moon
