We all have fear. It's a normal human emotion - we have a choice on how we respond to our fear.
We give power to what we focus on.
So if we focus on fear, the emotion rules us - it paralyzes us. But if we focus on what we need to do overcome fear, then we give power to our actions and we become courageous.
I love this saying:
There can be no courage if we do not have fear.
