Academics and beyond

If a person has interests in things like, comparative cultures, linguistics and gender studies… what would they do with something like that?

I mean… do they just go to grad school, study linguistics, sociology, maybe comparative cultures, or critical theory… research gender studies things… and write books?

Is teaching at a university the only academic career open to academically addicted people?

I’m an undergrad junior, and I’m starting to feel the pinch and the pressure from a certain professor who seems to think I could not only make it in a grad school program, but that it is imperative that I apply to one. And… I have no idea what to do, or where to start searching for the “why attend grad school.”

I don’t see myself happy outside of academia, but… is instructing/research the only carreer out there? what else can critical-theory or other similar liberal arts degrees translate into?
