Every story requires pain and suffering. If the protagonist doesn’t experience pain, he won’t change. “Pain develops character. If you have a story where someone learns through joy, the audience won’t buy it,” said Donald Miller at his Storyline conference.
Joy is great. Your story should incorporate some joy. But the Great Teacher is pain.
