What do you do when you know from the moment you get out of bed that you're set up to have a crap day?

Maybe because you’re stupid, stayed up too late, got on the computer at 2am instead of staying put in bed and trying to sleep again, got up and went to the bathroom twice in an hour and a half, got impatient again at 3:30 and went back on the computer, and when you finally fell asleep at around 4:30, your stupid friend thinks it’s a good idea to send 4 text messages in rapid succession at 6:15, half an hour before your alarm goes off.

Well then you forget to get gas on the way to work, even though you’re well aware that your car doesn’t like to start after you get gas if you’re under ¼ of a tank. And speaking of work, your co-worker is off on Tuesdays and you have to do her job, which you hate.

So how do you shove through? How do you resist going postal? What helps you slap on a happy face until you get to go home?
