on Writers in the Storm:
The change arc. The process whereby, over the course of a story, the protagonist becomes aware of their weakness and evolves in whatever way is necessary for them to achieve their story goal.
Joseph Campbell called this kind of character The Hero with a Thousand Faces because, while each protagonist is different and they each have their own problems, their journey is the same. Their success and happiness are being blocked by a specific flaw that must be dealt with. And most of the time, when their story begins, they’re blissfully unaware that there’s even a problem.
So how do we turn our ignorant, stuck character into someone who recognizes their fault and actively works to overcome it?
Yes, you read that right. Failure is the key to growth.
