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.
Mike TysonWhen I fight someone, I want to break his will. I want to take his manhood. I want to rip out his heart and show it to him.
Mike TysonI just did what I did in my era, basically because of my admiration for the guys who came before me. That's how I've always looked at it. I never thought of boxing like, I'm going to be the greatest fighter ever and make a lot of money. Instead, I thought I was going to win because I learned from the best. I carefully studied the videotapes of all the fighters from the past, dissected their styles, and entered the ring with their spirit.
