"its not homework unless it due tomorrow",the sense of urgency will be tomorrow night.
this is kind of vague, whats your point ?
I think what he means is this: Imagine you are given a week to do a particular assignment. So the day you get the assignment, you think, "I've got a week to do this, there is no need to get it done right now. I have plenty of time." So you procrastinate for the next week, doing other things, until the night before the project is due, and you panic. "Oh, crap," you think to yourself, "that assignment is due tomorrow, and I haven't even started on it!" So then you find yourself pulling an all-nighter to complete it, pressured to get it done right the night before it's due.
*shrug* At least that's what I get out of it.
