Metaphors for courage

Some words that could be a metaphor for courage: adventurousness, audacity, backbone, bravery, bravura, daring, dash, dauntlessness, determination, endurance, enterprise, fearlessness, firmness, fortitude, gallantry, gameness, grit, guts, hardihood, heroism, and intrepidity.

I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand.
