I know from the experience of watching my father working in engineering well into hes late 40s before pursuing hes passion and starting up hes own business building and selling custom motor bikes and being a lot happier when he did that.
That's my problem after fours years of hard work panic attacks when it comes to assignment deadlines and getting past those( closed booked programming exams always the hardest part of Uni)seeing other students ripping up their exam papers and walking out due to the pressure, watching my friends who did not choose to go to uni, going out all the time and having more fun/money whilst I'm stuck in my room studying head in my programming books(my favorite book is still the first one i bought second hand from amazon "C++ A Beginner's Guide by Herbert Schildt" a fantastic book, whilst working shitty part-time jobs for little money then at the end knowing I've got to pay off my student dept over the next 15 years.
I kinda thought I'd be more elated that i passed my degree but maybe I'm just being cynical and that's why i want to make sure i get the role I truly are passionate about straight away....
