Fear is the greatest obstacle to learning. But fear is your best friend. Fear is like fire. If you learn to control it, you let it work for you. If you don’t learn to control it, it’ll destroy you and everything around you. Like a snowball on a hill, you can pick it up and throw it or do anything you want with it before it starts rolling down, but once it rolls down and gets so big, it’ll crush you to death. So one must never allow fear to develop and build up without having control over it, because if you don’t you won’t be able to achieve your objective or save your life.

I don't want to be remembered. As long as my kids remember me, I'd rather be forgotten by everybody else.

I earned that the strong will always beat the weak, but the smart will beat the strong. Boxing is a tough guy sport. But in the end, the tough guy gets to clean the streets and be a bodyguard. In the ring, the tough guy is going to get hurt; at the end of the day, he's going to talk funny. Only the smartest win. So, I know it's cliché, but power - real power - comes from knowledge, comes from smarts.

You have to be a friend to yourself. You know, 'cause if you're not a friend to yourself, you're an enemy to yourself and if someone's a friend of everybody they are an enemy to themselves.

These pigeons have been living with each other for 10 or 15 years, but when I throw feed down, they kill each other to get it, and it's the same with the fighters. We love and respect each other...but we need that money.

Anyone with a grain of sense would know that if I punched my wife I would rip her head off. It's all lies. I have never laid a finger on her.

My main objective is to be professional but to kill him.
