My story is going nowhere. It seems like there is just too much going on inside my head. I write something and see that the story could go in so many directions that it's almost overwhelming. Each time I write something, I find myself adding another element to the story, and I'm afraid I'm making it all too complex. At most, I would say that there are 4 main characters, but there is a gigantic backdrop of people that live in the same town. So... I feel like I have too much to work with. I don't want readers to become confused. I don't want myself to be confused. Any advice?
