"You can't help but remember what Faulkner is alleged to have said when asked whether he wrote daily or only when the inspiration hit him. It's said he replied that he wrote only when the inspiration came, but that he made sure it came every morning at ten o'clock sharp when he sat down at his desk."
- Rick Bass

ah, the discipline of inspiration...a conundrum, to be sure, but a surer bet than winging it.
