So were mine, but that was mostly drinking at the fraternity house. Let's see, undergrad I had 2 majors (Physics and Chemistry) and 3 minors (Math, Botany and Political Science). I never took less than 15 hours, one semester I took 21 hours. I was in SPS (President for 2 years), Chemistry Club (Vice-President), Student Government, Student Council for the College of Natural Arts and Science (Secretary), I tutored, I did research in Physics and Chemistry (I even created a new fluorescence lab experiment for P-Chem), I had a job with the Physics department, and I was an officer in my Fraternity for 3 years. And it all fit in all nice and well leaving me with enough time to piss off most days of the week and get drunk with friends.
Undergrad was easy. Masters work was tougher, but still straight forward. PhD work kicked my ass and left me with no time (I only took 1 week off a year and that was around Christmas).
