Courage, contrary to popular belief, is not the absence of fear. Courage is the wisdom to act in spite of fear.--John-Roger and Peter McWilliams (Do It! Let's Get Off our Buts) 

Courage doesn't always roar. Sometimes courage is the little voice at the end of the day that says I'll try again tomorrow.--Mary Anne Radmacher 

Courage is a special kind of knowledge: the knowledge of how to fear what ought to be feared and how not to fear what ought no to be feared.--David Ben-Gurion 

Courage is contagious. When a brave man takes a stand, the spines of others are stiffened.--Billy Graham 

Courage is doing what you're afraid to do. There can be no courage unless you're scared.--Eddie Rickenbacker
