Should I go to UVa (in state) or Johns Hopkins? I don't know my major yet but definitely lib arts.

I feel like I’m too idealistic. I dont care about money and I dont want to be an engineer or anything. Maybe a film director or writer? Lawyer? I seriously dont know. Also, is JHU worth the cost?

No, JHU is not worth the extra expense over choosing UVa. Regardless of major, many students struggle to get a decent-paying job upon graduation. UVa is an excellent university, so you are lucky to be an in-state student. Go with the most affordable option and attend UVa.
