There's a crack in everything...

Often when a writer is having trouble with their story, when they are caught up with some perceived imperfection, a little delving (okay, maybe a little psychoanalysis, too) will help turn the "flaw" into some precious scene, or character trait or backstory or new way of writing that allows the heart of the story to shine through. Part of helping writers be successful is helping them learn to live with and sometimes embrace those things that make them uncomfortable. This is probably true for all kinds of artists.
