I'm stuck in the World Building trap. I'm trying to write a synopsis, an outline for my story, but I keep getting stuck on world building which is fine, except that I've been spending zero time actually writing the damn story. Whenever I want to sit down and write, I end up back in my world building document and jotting down ideas. I'm so busy writing ideas down that I'm not getting anything accomplished. Even though I recognize it I can't fins the discipline or patience to just sit down and write. Any advice?
