A story cannot simply be a series of remarkable events. You must start out as one version of yourself and end as something new. The change can be infinitesimal. It need not reflect an improvement in yourself or your character, but change must happen.
The old adage tells us that “the grass is always greener on the other side of the fence,” but the math tells us why: the unknown has a chance of being better, even if we actually expect it to be no different, or if it’s just as likely to be worse.
