Let's say that you decide that you are the sort of person who chooses to take an elevator that is going in an opposite direction from the one that you ultimately need to go. So, say, you go up to go down, rather than waiting for the down elevator, which might be full by the time it gets to you. If you do that, getting onto an elevator that's already quite full, GET OUT OF THE WAY WHEN YOU REACH THE TOP FLOOR BECAUSE IT IS TOTALLY FUCKING OBVIOUS THAT EVERYONE TRAPPED BEHIND YOU WAS ON AN ELEVATOR GOING UP AND SO PROBABLY THEY PLAN ON GETTING OFF OF THE ELEVATOR AT THE TOP FLOOR.
It does not make a good impression on your professors when you fail to do your reading assignments within the first two weeks of class. Nor does it make a good impression when you fail to bring the reading assignments with you to class, when it states EXPLICITLY in the course policies that you must do so in order to participate adequately. DO YOUR WORK FOR YOUR CLASSES OR YOU WASTE NOT ONLY YOUR TIME BY COMING TO CLASS BUT ALSO YOUR PROFESSOR'S TIME.
I could go on, but I'm going to go do work instead. Since this is the case, I will leave it to you, my readers, to add to this list should anything come to mind.
