Courage gives one strength, power, and endurance to overcome or surmount obstacles, weaknesses, hardships, and crises.
Courage is associated with bravery, valor, and heroism.
Bravery implies fearlessness in the face of danger, but courage may be shown in spite of fear. Valor defies danger. Valor is the strength, not of legs and arms, but of the heart and soul. Courage is habitual, contagious. We become brave by doing brave acts, Aristotle reminds us.
