I've still got it; I just can't aim it.

I turned out something like 1200 words today. Unfortunately, none of them were on the thing I'm supposed to be working on; instead, they were on the sort-of sequel. Which is doing its level best to eat my brain, despite my screams of "Not yet! Not yet!"

At this rate, I'm in real danger of writing all the fun bits before I officially start writing it.
