In the most simple form of story structure, a story features a character who has been destabilized by an event and then overcomes a series of challenges to restabilize their life. This is the story line for Star Wars, Romeo and Juliet, Tommy Boy, all the Avengers movies, and any rom-com you can name. Why do storytellers use this formula? Because it’s the most powerful tool in the world to captivate an audience’s attention.
