It's the emotional punches that you can't see that are just overwhelmingly devastating to your heart - your moral fiber.

To be successful in sports or business, you really have to live the lifestyle. Success is about lifestyle. Just because I was training and working hard, that didn't make me champion or a good fighter. My lifestyle made me a good fighter. In my mind and my daily life, I was the heavy weight champ when I was 15 or 14. I lived the life of the heavyweight champion, and that's who I became. And that is so much more than just training. So, when the time presented itself, that's who I already was. I was ready. I was already there.

I'm the best ever. I'm the most brutal and vicious, and most ruthless champion there's ever been. There's no one can stop me. Lennox is a conqueror? No, I'm Alexander, he's no Alexander. I'm the best ever! There's never been anybody as ruthless! I'm Sonny Liston, I'm Jack Dempsey. There's no one like me. I'm from their cloth. There's no one that can match me. My style is impetuous, my defense is impregnable, and I'm just ferocious. I want your heart! I want to eat his children! Praise be to Allah!

As long as we persevere and endure, we can get anything we want.

In order to be a friend to anybody, you have to be a friend to yourself. If you're not a friend to yourself, there's no way you're gonna have any friends.

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.

Unfortunately, sometimes you can't have fun accomplishing your goals. Sometimes people don't have the determination, the will, the steadfastness, the tenacity, they give in under the slightest struggle.
