The research is the easiest. The outline is the most fun. The first draft is the hardest, because every word of the outline has to be fleshed out. The rewrite is very satisfying. ↗
I used to think it was hard to write, and I still find the process more or less unpleasant, but if I know what I'm doing it rattles along, then the rewrite whips it into shape rather quickly. ↗
Like, every couple of months you read, they rewrite, you come back in, they've animated more stuff - they usually videotape you while you're reading it - so they'll incorporate some gestures and some facial expressions into it. ↗
So you have to keep waiting and then they give you the script and it's terrible. Then you have to go to the rewrite and they're very upset because you didn't like it. I went through that for seven years. ↗
Anyway, several rewrites later, Del Rey Books did publish my first novel, and it did become the first work of fiction on the New York Times trade paperback bestseller list. ↗
