One thing I realized this year, and it was a real D'oh! moment, was that it is much easier to whittle than to inflate. I wrote from a single POV with the intention to hit 50K words from which to carve a 35K – 40K novella.
I think that is much more doable than my previous winning entry which is 60K and needs another 20K added to it, at a minimum. (Which is probably why I have never gone back to it. Too much work.)
Next year, I may aim for a kids' novel. (They usually run between 30K to 40K.)
