To be courageous is a different feeling. Having no fears at all. Are you anytime sure you are not afraid of anything, not even worried? Get into a position to see what worse can happen. Implement your fear in a calculated manner before it comes to you in an unanticipated manner. What if everyone tried it. Sometimes making mistakes does not hurt. This one mistake can be known to us only. Nobody is watching you when you face your fears.
Give it a try.
