Courage is like love; it must have hope for nourishment.
Napoleon understood something that makes him unexpectedly wise on matters of the heart: courage and love aren't solitary virtues that spring from iron will, but interdependent forces that wither without belief in possibility. Most people think courage means acting despite fear, but he's saying it's something more fragile—it requires you to imagine a future worth fighting for, otherwise resolve simply dies of starvation. A soldier can charge into battle on adrenaline alone, but a parent staying in a difficult marriage to heal it, or someone returning to school after repeated failures, needs the specific nourishment of *hope*—the conviction that things can genuinely change—or they'll eventually collapse. This explains why despair is courage's true opposite, not cowardice.
