I'm the best fighter in the world. No one can beat me....My objective is to inflict as much pain as possible, to win and win spectacularly...Ever since I was 12 years old, I was groomed to be the heavyweight champion of the world. I've been prepared to handle the pressure, the dealing with the press, everything.

I never look at a high point in my career. Everyone thinks about the Spinks fight, but that fight only lasted 91 seconds, so it's hard to say it defined my career.

That's what people respect, the fact that I wasn't a chump that laid on his back and gave up.

What was most important was the knowledge [aspect] of the fight. I learned this early on and just told myself to "upgrade my mind." That's just what I wanted to do my whole life.

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 feel like sometimes that I was not meant for this society.

It's good to know how to read, but it's dangerous to know how to read and not how to interpret what you're reading.
