The short answer: a lot more writing.
And as much as I usually like to elaborate, I just don’t have the energy or time to say much more right now. Part of that is just hanging over from the doldrums I suffered all November long, but the other part is that I need to use my time (tiny slivers of it, at least) to continue writing this year’s novel.
I wrote my 50,000 words before the end of the month (54,000, actually), but I am nowhere near finished with the first draft of my book. So instead of writing about writing (even though I love to do it), I am going to just plain write for a change.
