I think writing is largely about trust. You have to trust that things will unfold okay.
At around 35k words on the novel I’m working with (my first), I hit a block. I suddenly became aware that I am not, in any way, at all, cut out for the long form of a novel. My plot had become ridiculously complex and although I knew where the climax would go when I got there, I had no way to get to it. My writing became rambly and general and booo-oooring. I was bored to tears myself, so I can only imagine how a reader would feel.
Fortunately, an old professor of mine who is connected with me on Facebook (Chella Courington), posted this from Richard Bausch at about the same time:
Most of the trouble you have with writing anything is temporary–if you can manage to think only in terms of this one day’s work, while holding back anything other than the determination to stay there the appointed amount of time and struggle with it. As I’ve said many times, most everything ever written was written a little at a time, over time, in a lot of confusion and doubt. It’s the territory. Quite normal and all good. If you’re spending the time, confused or no, happy or no, it is all going very well indeed, even when it feels like failure.
So the next morning, I got up again and wrestled for an hour. And guess what? The story started to make sense again, the path cleared before me like a fog lifting. Only a little, mind you. I can’t see to the end of the path yet. Just enough, and just enough is enough. Scene by scene, bird by bird. Keep wrestling, and trust. Trust that it will unfold.
