Too bad you were not born in Europe! Most of my European friends speak at least four languages! I have an Italian friend who speaks Italian, English, French, Spanish, Portuguese, Latin, and is teaching herself Chinese and German! I only dabbled slightly into French, German, Italian and little bit of Latin.
I would recommend one to learn languages by system, i.e. related languages. For example, learning Italian will make learning Portuguese and Spanish much more efficient. This will make your life easier. You will see how one language influenced another, and how it all connects.
I listed Italian first because we are all familiar with the musical terms, and you may not realise it, but it adds up to a decent vocabulary base (piu forte is a term you can use in bed too!). Either way, good luck with your goal.
