Here’s a tip for everyone doing NaNoWriMo.
Say while you’re working on your book you get an idea for a decent 2-4K short story, but are uncertain whether you should take a break long enough to write it.
Now this isn’t an instance of “I think this’ll make a good story”. No, this is the story has more or less bubbled forth fully formed out of the froth of your NaNoWriMo-fevered brain, and since you’ve been putting in long hours pounding the keys you KNOW you can write this story, polish it, and get it out the door in 24 to 48 hours.
Well, if that’s the case, and you’re at all interested in actually completing some decent fiction this month, then take the break and write the story.
Your novel draft can wait. Inspiration won’t.
