Use “FOR EXAMPLE”.
When your protagonist first appears, devise a scene in which the main flaw shows in action.
If the flaw she must overcome to achieve her goal is her extreme selfishness, give us a visual EXAMPLE that blows her selfishness up larger than life. When the second act rolls up with the conflict that she must complete community service or go to jail, we can see why there’s no way she’s going to make it.
To show her selfishness, FOR EXAMPLE, when we meet her, she’s running late, so she takes someone else’s coffee at Starbucks, then deliberately shuts the elevator door on a guy with crutches.
She’s primed for a relatable journey of difficult change. Match the flaw to the challenge to create natural conflict, and use EXAMPLES in action to show how she’s progressing.
