It's not time for the post-novel ennui. You have not finished a novel recently. While I acknowledge that the Chill CEM was a rather large task, which you accomplished in record time, maybe you should consider getting on the stick with either the vignette you are meant to be writing or the actual plot for The White City, which is, I note, stalled at something like two-thirds done.
The problem with creative work is that it's. well. creative. Which means a lot of it takes place down in the soup, and will not be rushed.
Ah well. There are a lot of deadlines, it's true. But none of them are currently pressing. I can give all this some cooking time.
