I have a lot of things in my head.
I've had a few random ideas for my current story, involving time travel, human sacrifice, the usual. I also have this gnawing in my brain, in my very soul, to finish The Long Road.
I don't know why that story is so important. I mean, every year, I sit down to write a NaNo novel, and I say, "This will be the one." The Great American Novel. The story that's going to change the world, even if it's just my little corner of it. It's the story that will make sense and I'll be able to show it to everyone without cringing. Every year, I say that.
And every year, I write a pile of complete nonsense, with a few good gems sprinkled throughout, the needles in my haystack.
