My commute to class is about a mile at best, so I look at it as a full sprint. It means I can wake up 2-3 minutes before my class, pull some pants on and race over to get there on time. Helps to wake me up a little too. I'm so used to the traffic and parking on that road that I keep getting there faster and faster. I really wouldn't mind a longer commute though, except on rainy days.
