I won't tell anyone. I promise.

But you know what? I've been in the military for over twenty years now, and I've been scared lots of times. But I never failed in my objectives because of it. Fear can keep you sharp. Fear is just survival instinct and your survival instinct can help you stay alive when things get dangerous. The secret isn't to stop being afraid but to just keep on doing what you've got to do anyway and learn not to let it control your actions.
