I would be interested in seeing this expanded to talk about what the change you can create by stopping is.
My initial thought is that humans have to exist in one of these stories to participate in society, but stopping could allow you to realize you want to change stories completely.
Maybe it is also possible to dramatically influence the story you are already in, but this seems less likely as the other characters would have to accept that change.
A concrete example of this is giving up drinking. If you give up drinking you usually need new friends. You won't enjoy the story anymore because you aren't drinking, and your old friends won't want a downer like you around.
