Or, embrace your process. I've come to realize that I'm more creative/productive doing a lot of things. Because if I get stuck on one thing, I switch and keep moving forward. If I'm on one thing and I get stuck...the stuck has a lot of impact on my productivity, and is also discouraging as hell.
Which is why I've decided to be okay with writing four books at a time while reading ten.
I've also decided it's okay to have a process that's a mish-mash of planning and discovery in the moment. Sometimes you have to plan ahead. Sometimes you don't know how to plan because something hasn't been discovered yet. This thought brought to you by Candace Haven's Mozart or Beethoven? post on Genreality. I couldn't answer the question until I admitted I do it both ways. In the same book. Sometimes a scene is just there, whole-cloth. Sometimes I have to figure it out, one random and disjointed piece at a time.
While I'm at it, I've decided it's also perfectly healthy that I get all cheerful plotting fictional murders and violence.
If you've tried to change something about yourself or your process and gotten discouraged, why not just make a virtue of your vices and go with it?
