I’m passing this on, because they tell me it’s something people tend to overlook when they start NaNo. If you win your NaNoWriMo you are minimum of 30.000 words short of a novel.
Okay, so option 2 and 3. Think about this; is there a way you can not cheat and still do this? Like, short stories set in the universe of your main story? Things you can maybe even turn into sub plots down the line. Is there something you can turn into lore, some big event that will have happened and maybe even impact the decisions of your main characters?
But, rebel away. I’m rebelling this year too. My new idea is in the queue, awaiting proper research. :)
