Ironically, having hammered out my quota and no more on Nano, I had a wild idea on something totally unrelated and wrote 3K words on it.
I suspect this may be an interesting form of procrastination on the part of my brain–“I’m tired of this idea. Ooo! Look here! Look at the shiny new idea! Dance, monkey, dance!” but you never know.
There is absolutely no way to combine the two, unfortunately. I wish there were.
