What to Write?

I'm looking at three weeks between now and the start of Camp NaNoWriMo, and taking Dean Wesley Smith's advice to produce new words every day more to heart, and wanting to produce more short stories to post for free here and then later to package into collections and sell. So I've got ideas for some weird (fantasy/fantasy-ish) super-short/flash fiction, and I'm looking through old notes and story fragments, and what happens? One fragment, just a couple of paragraphs and a few lines of dialogue, decides to morph into a novella set in my Estelend world and loosely connected to Chosen of Azara.

And now I'm going, AAAHHH! what to write! what to write!! There are eighteen days from today to the start of Camp NaNo (excluding Sundays, which I take off from writing) and including today and March 25th, my jury duty day (hopefully I can get some writing done while I'm hanging out in the jury waiting room, and hopefully I don't get rescheduled to sometime in April). At a minimum of a thousand words a day, that's eighteen thousand words. Figure an average of 1500 words for each of my super-short stories, so that's 4500 words, leaves 13,500 words for the novella. Not sure that's quite enough, but if I up my word count to 1500 a day (also very doable) that'll leave me with 22,500 words for the novella, to write before April.

Can I do it?
