I'm doing three subjects at the moment too, which is like, 8 contact hours a week for me. I could handle 4, but I figured that I've worked hard in summer semesters and in high school to get 'ahead' in my degree, so it doesn't feel like slacking. This is also my first semester where I haven't totally freaked out. I've started to realise that there are things as important as uni work to put on my to do list, and the way I've prioritised my life may well be the recommended way to do things, but it's pretty unfullfilling.
My job is all over the place in terms of hours, but it's been 10 hours a week on average recently. I like work, it pays really well and it makes me feel as though I'm doing something that not just anybody could do, and it's not completely mind-numbing like retail was.
My social life is really nice too, I'm living in a share-flat with friends, and we go out actually quite often. I've been drinking much much less so far this year though. More going out for dinner or coffee or whatever.
I really vaslue my new found flexibility, I study as much as I need to and I can fit in anything, really. I hope you find the balance too...
