Courage is like love it must have hope for nourishment.

Bravery runs on fuel, and the fuel is some belief that acting could matter. Without it, courage does not turn into cowardice; it turns into exhaustion, which looks similar from outside and feels entirely different. People who have been ground down are not weak, they are unfed. Restoring the sense that effort can change something restores the nerve along with it.

If your own courage has thinned lately, do not start with resolutions. Look for one small case where your action clearly produced a result, and let that register properly. Feeding hope in concrete ways rebuilds the willingness to act better than any instruction to be braver.
