Mmmm, similar story here. I worked an average 20 hours a week in a restaurant, which when added to scheduled classes was already a full 'working week', and then the actual work started - despite the part-time work, I was very dependent on bursaries and scholarships to cover my fees (which were almost exactly my annual earnings), so needed to keep getting the marks. I remember having to ditch one 'student' activity after another to make time until the only college-type events I was attending were specifically related to my courses (field trips, conferences), and then endure constant slagging from my kitchen workmates over my lazy student lifestyle. These gibes continued for four years until my git of a thesis supervisor came into the restaurant one night and spotted me in my stripy apron and silly paper hat, and asked me none-too-quietly "Could you not find a more suitable job?", which earned me a temporary pass from angered staff. Not to say I didn't enjoy the whole college thing hugely throughout, but it certainly wasn't a doddle (it was however nothing on the workload I experienced my first-and-only year as a lecturer, which was literally 18 hours a day 7 days a week, and the hardest job I have ever had).
Of course unless I have formed a completely mistaken impression of Mr. Gloady, both of us were pretty interested in what we were studying, so it probably makes a difference...
