One of my favorite aspects of developing a character’s arc is exploring their false beliefbecause it’s key to the emotional heart of our story: a character’s struggles and journey toward change. Without a false belief established—that they then attempt to overcome—we’re more likely to have a hard time coming up with strong or interesting story events beyond just external plot obstacles.
If you’re not familiar with the concept, a character’s false beliefs are things the character believes that we, as the author, know not to be true. They’re not really unlovable, not everyone is out to get them, trust isn’t always a lie, etc.
