Not really. I mean, I don't literally have hives from my book. I'm not really sure what hives even are. But I've been adding an element to the story, a last minute change that really helps tie the plot together better than it had been.
I take notes. Sure, they're scribbled on a piece of scrap paper, but I know where the paper is. Still, I keep worrying that I'm going to forget something vital. It's a dumb worry, because I won't, or if I do I'll find it in my last pass through the book. And if I miss something, my agent will probably catch it. And if she misses it, I'll probably catch it on the
next editing pass.
Yet my stupid brain keeps telling me, "Don't forget about the phone! Don't forget about the notepad or the key! And you still need to revise chapter one again!" It even uses all those exclamation marks.
