Personally, none of those would be MY first choices. When I go back to college next quarter I'm going to take Japanese and Arabic if it's available. Arabic because it will help me with my position at the CIA and Japanese because it will help me and also because I want to. I MIGHT take some more languages, it just depends on the situation.
Italian and Spanish are too fucking similar. I personally would probably take German over Italian even though I'm more Italian than I am German but the German language is better. If you want to speak something powerful, go with German. If you want to speak something weak, go with French. No offense Frenchies, I'm also French (I have more nationalities than most) but your language is weak and I personally have a grudge against your country.
