The other thing too, for NTP's I think, is that if everything is all planned out, then it takes creativity out of the equation. It just becomes about following a list. About 3 days of that and I start to feel like a drone or a robot. I get off on reacting to things "on the fly", having to improvise. I make my best decisions when I have to react to something RIGHT NOW - not 4 days ahead of time.
