1:15AM, my friend/colleague leaving my apartment:
"Yeah, I'm heading out. You going to bed?"
"Nah, I've still got a few things I want to do."
"Why not sleep and get at them in the morning?"
"Because..."
"When I try to work late and I haven't covered everything, I do sloppy half-productive work and don't get anything done. And then sleep later or get less sleep. Both are bad, so why not just go to sleep now and get at it tomorrow?"
"Yeah, you're totally right, but I'm going to put some half-ass working hours in and do precisely what you described."
He shrugs. "Okay, see you on Monday."
Two hours later...
(Well, at least I got this blog post written)
