I feel your pain, although here in Asia many work 9-830 and then somehow on the weekend try and do stuff that matters. My experience is that it's good pressure as it forces you early on to be judicious with your time and only do what really needs doing NOW and with some kind of order. It also prepares you slowly for the discipline and loneliness of being a full-time entrepreneur. So try and be positive as sounds like you have reason to be! Lets face it when you grow up its harder to find butterflies:)
