Stage two of plotting for the Heroic Journey: Making Progresss
At about the 20 percent point of the story, corresponding to the end of Act I in the three-act drama structure, there’s the First Reversal. Something happens to transform the Hero’s new situation into a new desire and a change of plans. This will set the Hero’s external motivation for the rest of the novel, and the action is underway.
The Hero enters the Mythological Woods by crossing the Threshold. He journeys through strange yet deeply familiar forces, learning new rules and being tested, overcoming obstacles and conflicts.
