Actually, I am in a similar position. My major is international studies, and in looking back I realized I hated nearly all the required classes I've had to take for it. Of course, the language classes I've taken (which are required too) have been amazing, and I've loved the elective classes too--most of which were political science classes. When I think about it, maybe it would have made more sense for me to be a poli sci major, but I don't regret my choice per se.
As far as career choices go, I have no idea what I want to do (still), so I couldn't say whether or not my job will be centered around my major. I have a feeling it won't, though. Nonetheless, I hope I get something that can at least help me make the most of my language knowledge...
