There can be no courage unless you're scared. Courage is the ability to overcome fear and take action.
Courage is the ability to feel the fear and do it anyway.
More often than not, the fear is worse than the thing that is feared. And fear can make you very resourceful. It heightens the senses. It provides the energy you need to confront whatever it is you fear. When you decide to use your fear, rather than fear it, it becomes very useful.
