I begin to see why so many children's books have one sibling designated as "the clever one": when you are deliberately having three children clever in different ways, it can get to be hard to balance who thinks of what when. Some of it is clearly in the category of "X would think of that and Y never would," but some of it is just that something needs to occur to someone, and it would eventually occur to all of them, but someone has to say it first.
I have not drafted a book this year. This is the first year since 2000 in which I have not finished the first draft of a book. I don't particularly like this, but I also think that this is exactly the wrong time for me to push through to finish a book in a month. There's a reason the NaNo people didn't choose December, and besides, I just don't feel that great. So I will keep doing what I have been doing: revisions, new writing, sending stuff out. Generally keeping on as much as I can. It's not that I haven't been working. It's mostly that Thermionic Night and Sampo have required a lot of work, and I haven't had as much energy to apply to that as I usually do. I know I'm not being a slacker.
It still bothers me, though.
