Good writing is often designed around a character who has a distorted vision of himself or of the world. During the story, he is placed under sufficient pressure to force an epiphany, a moment of clarity in which, he sees the world as it is, not as he wished it to be.
A classic example is “Casablanca,” where Bogart’s immortal Rick has managed to create an insular world in which he can pretend to be utterly detached and uninvolved. He supposedly has no political beliefs, and no real human connections. But the reappearance of Ilsa forces a cascade of events that cause Rick to reexamine his attitudes about love, fate, patriotism, courage, fidelity, friendship, and life itself.
Rick begins as a damaged, closed off character, carrying wounds to his heart and ego. What he WANTS is to be left alone to his self-pity. What he NEEDS is to be re-awakened to a life of purpose. The writers, wisely, give Rick what he needs, not what he wants, and in that manner a classic was born.
