Courage is not the absence of fear, but rather the judgement that something else is more important than fear.
Fear is natural and a good thing. Everybody has fear and everybody has a lot of fear.
Fear is your mind telling you to be cautious wich is great. But you have to be able to cope with it. Know that fear is nothing dangerous or something to be afraid of. Use your fear, embrace it and still make rational decisions.
Fear is like a human being always yelling at you before you make something dangerous. You can run away scared or make the deliberate decision that this fear-guy has to shut up for a minute because you need to kick some ass!
