In college I had a classmate who would do that. He was a straight A student, he HAD to get an A. But he was also addicted to WoW. So he'd play WoW till like 2am, then study till like 4am, and then be in the next day at 8:00am. He'd pretty much be bloodshot all the time.
He ended up flunking because of one course. The TR project, which was a project we had all year to work on. he just procrastinated that project for the entire year and never ended up handing in anything. Not even a 1 night attempt at something.
I think it would have been funny if he made his TR project on procrastination and did it all the night before. I bet he could have gotten a pass due to the hilarious irony.
