I haven't started. I ought to be starting now, but instead I'm getting some time in on the procrastination.
I don't have a lot of faith in my idea, which is pretty open-ended to begin with. I'm planning to tread water until the weekend, when I can chat to my local group and get a bit of energy going.
I often completely fail to plan anything, except maybe an opening scene and one major incident. A couple of years ago I ended up writing a book called
The Incredibly Tedious Life of Arthur Dull because I hadn't had any appealing ideas by November 1st. (I did finish it, and his life didn't end up all that dull, but it's not a very coherent novel, and no one else will ever see it.)
I have also, in the past, threatened to write a Nano based on the output of
They Fight Crime. I'm hoping it won't come to that, this year.
