National Novel Writing Month is in November. The goal is to write 50,000 words in 30 days. I've never participated, but I did my own Novel Writing Month in September. I drafted my book from start to finish in 53,456 words in 30 days. I later went back through and added a few details and fleshed out skimpy scenes, and counted that as still the first draft, so in the end the draft was about 60,000. Decent for a first draft. My target for the book is about 80,000. (It has no title yet. The placeholder title is Simi.)
It helped that I outlined the book in August. I wouldn't succeed as a pantser. I wouldn't come up with anything decent. When I wrote Beyond the Mountain I knew the whole story beforehand, but didn't know what I was doing, and pantsed my way through it. The pantsed parts weren't so great. For Simi, I outlined as much as I could beforehand. I highly recommend Janice Hardy's Outlining Your Novel. She has you brainstorm a lot of aspects of your story, and the exercises have you write a lot down so you can see where you have gaps. (I also tried Libbie Hawker's Take Off Your Pants. It seemed okay for writers who already have a pretty good idea of their plot, but it doesn't take you through any brainstorming. I'll give it one more try on my next book.)
It also helped that I was on a time constraint. For Beyond the Mountain, I researched as I wrote, and it took me about 8 months to write the first draft. For Simi I wrote first, and now I need to do a bit of research to fact check and add setting details. I hope doing it this way won't take as long. Rather than researching everything and seeing what I can fit into the book, I'll be researching only the things I need to know.
Now comes revisions. There are a lot of books and websites dedicated to plot, structure, character arcs, writing fast, letting your first draft be sloppy, theme, and writing style. But I haven't seen many on revision. Revision for me usually means staring at the screen and knowing what my problem is, but not knowing how to fix it. And without a time constraint (why is there no NaNoRevMo?) it's easy to procastinate. Fortunately Simi had a pretty clean first draft, so that's a step forward already.
I'm getting closer to publishable-ness with Beyond the Mountain as well. I've had one round of beta readers, and I know where it needs work. Now to figure out what to do about that.
