What was your undergrad in? Me, I vote you do English Lit, but I have nothing to support that with. You're bright, and you can obviously read piles and piles.
That is what I got my undergrad in. And I like all those liberal arts degrees. But I'm fantasizing about what to do to burnish my resume. So I'm trying to figure out something that doesn't take me out of commission for years and years and is not an MBA or an unrelated academic field. (I know an MBA is useful but I hate the part where you work in groups to do business-y stuff. I'd just want to learn the theory, not the practice.) A friend suggested the London School of Economics-- that sounds fancy, right?
