Boxing is a sport of self-control. You must understand fear so you can manipulate it. Fear is like fire. You can make it work for you: it can warm you in the winter, cook your food when you’re hungry, give you light when you are in the dark, and produce energy. Let it go out of control and it can hurt you, even kill you… Fear is a friend of exceptional people. I should add that at no time does fear disappear. It’s just as bad in the hundredth fight as it was in the first, except by the time he reaches a hundred fights or long before that he’s developed enough discipline where he can learn to live with it, which is the object, to learn to live with it.
