Our word "courage" comes form the French word coeur, "heart." Courage is a willingness to act from the heart, to let your heart lead the way, not knowing what will be required of you next, and if you can do it.
Thou sweet Well for all who thirsteth in the desert! It is closed to the one who speaks, but it is open to all who are silent. When the one who is silent comes, lo, that one finds the Well.
