"Oooh! Ooh! Pick ME!"

I have a book idea, a SF story, that's rattling around in my head, busy trying to get written. I'm being disciplined and while I wrote down notes for it and characters, the sketch of the plot, I haven't indulged myself and started work on it, since I have to eat my broccoli (wait, I actually like broccoli) -- but I'm working through the finalization of the book I mentioned the other day before I launch into something new. Maybe (maybe) when I get that one finalized, I'll dive in and work on that new one -- I imagine it trying like hell to get my attention from the back of the line: "Me! Me! Oh, pick me!!" So, I just might do that, because I think the story has a good concept, and a lot of potential, and because, so far, I haven't actually written a SF novel (I have a SF novella I've been slowly expanding to novel length, but that's it). Thus, it'll be new ground for me, which'll make it more fun.
