I am a high school freshman, what can I do in life with a knack for picking up foreign language?

I have a pretty good idea already. I plan on, throughout my high school career, taking all levels of the Spanish courses, all levels of French, and one level of Mandarin Chinese.

I seem to be good with picking up language and constantly try to think of ways that I could say what's happening in my current situation, but in Spanish. I've been writing in coded pigpen since about 3rd grade and my personality psych profile mentions skill in foreign language. I plan on being at least quentilingual by the time I die, counting sign-language.

So I beg the question, what can I do after high school? What specific degree would I look for, what colleges are VERY good for that major, what kind of careers would I be able to score, and at what type of employer?

I know the Alphabet soup agencies hire many linguists, I know of internship opportunities in one such agency, but I do not really want a government job. Can someone describe to me some careers that wouldn't that are available that also wouldn't be obvious to the average dummy?
