Sometimes it's a blessing when you're so keyed into an idea that you can't sleep for wanting to writing it. Sometimes it's a plague because the idea is pathetically out of your league, unrealistic and without a shred of hope of ever seeing the light of day. It sits there in the back of your head, like a tumor, festering until you must do something, anything, to free yourself of it. Whaddaya do? Write the damn thing anyway. (And then maybe post it to the internet for the wolves who won't appreciate it anyway? I dunno, I'll let ya know.)
