I disagree with a part of this definition. Courage is not the ability to do something difficult, dangerous, painful etc, without fear it is to do it in-spite of that fear. Everyone is afraid of something. I have many fears – some are founded others are just silly to others.
Fear is one of those things that can paralyze some and others it spurs them into moving, making them look courageous. You aren’t courageous because you are doing something you are afraid of. You are courageous because you didn’t let fear stop you from doing it. It takes a lot to conquer your fears – that takes courage. But that does not stop you from being afraid.
I can ride an elevator or an airplane. It takes courage for me to do that. But I’m still terrified. But I don’t let my fear dictate my life.
