I love studying! I'd do it forever if I could (and in fact, in an ideal world, I would prefer to work in retail-type jobs and fund endless degrees, although this isn't possible if I want to stay in Europe). I suspect, however, that what I like is the friendships you make as a student, which in my experience are impossible to replicate elsewhere. And as I get older, I may find it less appealing to hang out with a bunch of people in their early 20s.
