Here's the thing, when you power through the fear, overcome it and push through to the needed solution, that fear recedes. Having the courage to act in spite of the fear mitigate that fear. We can shrivel our fears to nearly not there if we act with courage.

I think there's a difference, however subtle, to feeling fear and actually being afraid. In my mind, being afraid is being held back by your fear. Fear isn't opposite of courage. Being afraid is.
