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.

The hero and the coward both feel the same thing, but the hero uses his fear, projects it onto his opponent, while the coward runs. It's the same thing, fear, but it's what you do with it that matters.

There are very few new things in this world, very few. That's why people that are young, if they're smart, try to profit from the experience of an older guy so they won't have to go through all the pain and suffering. But a certain amount of pain and suffer is good, because it makes a person think they've learned.
