Writing is a great method of psychological hygiene. If you use the National Novel Writing Month for the purpose of unburdening yourself psychologically in preparation for the emotionally taxing winter months, that’s great. However, the moment that even the slightest whiff of a fantasy about eventually publishing the product of this writing and making money from it attaches to the endeavor, you need to know that you have walked into the realm of pathology.
Many people escape from the realization that they are not very happy with their lives using fantasies of writing a bestseller, becoming a rock star, inventing something that would make them millions, etc. If you need to hide from reality in these fantasies, that’s not a good sign. It would be a lot more effective to invest the time you waste each November on churning out the words nobody ever wanted to read into figuring out why you dislike your actual life so much.
People who suffer from midlife crises are precisely the ones who kept avoiding the realization that they hated their lives until such an avoidance became impossible.
