Little-known rules of marathon novel-writing:
1. Never stop writing at the tidy conclusion of a scene, because you'll have really no motivation to move on to the next piece of action.
2. Never decide you're good on word count so you're just going to knit through lunch instead of write, because you will find yourself siezed by an idea at 3:06 p.m. and no time to write any of it down.
3. Don't let your characters smoke inside the novel, because the non-smokers start coughing and waving their hands all around and making a big scene about it which, frankly, is just upsetting to everyone and does nothing to further the word count.
PS, why do I feel like everyone's already reached 10k and I'm just treading water here?
