Well, _I_ learned in college that people vary widely in when and how they are most productive, and that trying to change your nature is an uphill battle. Obviously doing the work two weeks ago when you knew it was approaching due would have been the best method, but there are times when the crunch is unavoidable (OP) or when you chose life-enriching activities over work (college). For us night owls, when the deadline is imminent, the all-nighter is the surefire way to pull it out.
