I do not believe in writer's block. To even write about writer's block indicates that 'block' is not real. I do believe in creative standstills, where you're facing a writing problem (i.e. what should my character do next? how do I make such and such more believeable to the reader).
I also understand it when you get out of your writerly rhythm.
That seems to be the place that I'm in right now. The real world has crept very far into my conciousness, for one. I've also been in editing mode for quite a while now--the 'let's make everything pretty' mode.
I've also let myself sink into "What will my writer's group think if I don't do XYZ?" I've debated about what novel to continue with, whether I should remain in editing mode and submit an old novel while I rework it. That plan included working on something new at the same time. However, I can't switch modes that quickly. I can write two things at once, or I can edit two things at once. I cannot edit one thing while working on another thing. This is a new discovery.
So, addendum to the new plan: revert back to the old plan. Write, write, write.
Then I guess next year will be edit, edit, edit.
