Thought I'd chip in with my 2 cents.
I've just finished my second year doing computer science, I hate my course, it bores the nadgers off me, I only did it cos I didnt know what to do in life after my A-levels, I got an A at A-level in computing so thought I might as well. I was always a shy kid at school/college so I did wonder if I could handle it. I always had images of turning into the guy who sat at his computer all day that would never get laid or have any friends.
As it turns out uni is/was the best thing I've ever done, first year I had a blast, went out loads, got drunk all the time an made a few good mates, met my girlfriend who i'm head over heels in love with and I improved my social/communication skills one million percent. However I still worked hard, got fairly good results in exams and spent a lot of time working as I struggled with some aspects of the course. Very much the same thing in the second year with just slightly less partying.
I'm also in a fair bit of debt, will be owing 10k when I finish, however thats partly my fault because I've just been to the Maldives on holiday with the gf and we're goin to Oz after our finals next year and if I can scrape enough we'll go back to the Maldives soon after. But hey, I work my arse off in the holidays to pay for it so its not like i'm slacking around, yes the money could pay off the debt but its the last chance before I have to get a proper job and have to knucle down, I'm gonna enjoy it while I can.
As for the student stereotype I think in many cases its correct, there are exceptions but you have to accept there are different levels of 'studentness', take my uni house for example:
me and the gf, very similar, described above
male 1: stoner, does psycology, doesnt turn up for anything
male 2: financial course, rapidly turning into male 1
male 3: unbeleivably lazy, misses most lectures
female 1: does history, only 4 hours a week, spends most of her time watching tv
female 2: does 30 hours a week studying food, tries real hard and does ok, doesnt go out that much
So yea I may not get anywhere with my degree, but its the experience thats helped me improve as a person and I've loved every second of it. None of my mates have gone 2 uni, they're all on apprenticships and such earning no money but could soon be on 50k, but guess what, they all wish they went to uni and are regretting it. I'd rather be on no money but be happy and had enjoyed my 3 years rather than be on 100k sitting around moping and complaining about tax dodging students!!
