Welcome to January 2015, folks! For me, January means Nanowrimo editing.
I take December off because heck, I just wrote for a solid month, and I deserve it. Also holidays.
Here are some tips for editing in January.
1. Reread before you edit.
This is SO IMPORTANT. If, like me, you have taken a break before editing, then you need to re-familiarize yourself. You can't edit something you're unfamiliar with.
2. Yes, the whole thing.
I MEAN IT. The whole idea of Nanowrimo is that you write without editing, without going back. Because of this, it's easy to forget certain key things that happen in your novel. You cannot edit what you are not familiar with.
3. Start with the main plot.
The big things have to be in order. Look over your plot, and if something doesn't make sense, move it around or cut it out.
4. Move on to subplots.
After you've edited your main plot, some of your subplots may need to be moved around or deleted. They may just no longer be relevant once the main plot has been changed. If you like a subplot for the story, but it no longer works, you could try adjusting it for different characters.
5. THEN fix any spelling or grammar mistakes.
If you start with this, then you'll get caught up in the minutiae, making it harder to see the big picture with the plot.
