On writing when everyone else is asleep

"You never have to change anything you got up in the middle of the night to write.."
Saul Bellow

I might disagree with the "never" part, but I'll admit middle-of-the-night writing jags are pretty inspirational in their own right. If you can live without the sleep, the magic of writing when the rest of the world around you is quiet can be intoxicating.
