Stories are about change. Our characters’ world is changing around them, or they’re changing internally—or both.
Yet at the same time, we know change is hard.
In our own lives, we struggle to change our habits or take steps to be successful and reach our goals, whether that’s switching jobs, getting into shape, or whatever. In fact, we often resist more the closer we get to the possibility.
Just because we know what we need to do doesn’t mean we follow through.
