Already speak Swedish, English, Japanese and German. Swedish because I'm Swedish (big surprise), English because we all study it in school from when we are 7 years old (and I'm fine with that, good language to know), Japanese because I've studied it and live in Tokyo since a few years back and German because, when entering junior-high all Swedish students have to choose between German, French and Spanish as a third language.
The language I really wish I had studied is Italian. I LOVE Italian football and if I got to live twice I would have loved to move to Torino instead of Tokyo, learn fluent Italian, go to a university there and then find a good job, all the while having a season-pass with my beloved team Juventus.
There just isn't enough time =/
