If you like to plan your stories ahead, you’ve almost certainly sketched out your plot. But have you planned your character arcs? Every story needs a character arc for its protagonist, even if it’s simple or subtly conveyed. And while supporting characters don’t always need an arc, stories are better off when they’re included.
Luckily, characters arcs work very much like any other plot strand you might be working on. The difference is that they focus on inner events rather than external ones, which can make them harder to wrap your head around. If you have a character that needs an arc and you’re not sure how to add one, these steps will get you started.
