Being able to create things is a valuable skill in my opinion. I can´t build anything, except if you want to call wrinting stuff "building" something...ah well, I´ve always been better at destroying stuff I guess :D
Concerning the languages, I´ve always been glad to be from a non-english-speaking country. Essentially that gives me one language for free since english is pretty easy to learn after all. I think if you are able to speak english, you´re pretty much set in most of the western world. Okay, french and spanish are pretty handy languages all around the world (thanks, colonianism) but apart from that?
Take german for example. What good would it do an american to learn german? It´s not like you can speak it in that many countries. Okay, it´s probably more useful than learning...hmm...croatic for example or maybe polish.
Funfact: I always feel bad when I speak german in the netherlands. Almost everyone there seems to speak german (with that adorable acent

) but I somehow feel bad about that they understand my language but I can´t understand theirs.
Ah well, at least german is a good shouting-language thanks to Hollywood.
ACHTUNG! SCHNAPS! or simply VERBOTEN! (which doesn´t make much sense all by itself).
Anyway, what language would you have liked to learn, Ghost? If you had the time and motivation. I don´t even know what they offer you over in the US. French? Italian? Spanish I guess...hm.
