Fluent in English, French, Urdu and Punjabi.
I'm decent at German but hope to become fluent within a few years.
After that, I would like to try learning Spanish but anymore than that would be too much as I couldn't practice them all at the same time.
Well, I wouldn't forget French, English and Punjabi even if I never use them again, but the others require practice. I love hearing and learning basic words in languages like Greek, Italian, Norse, Icelandic, Farsi, Romanian, Dutch, Catalan, Pashto, Romansh,... But I'm probably never learning them, just being fluent in Spanish and German would be awesome.
It's a one-dimensional mix as all of them are spoken in similar areas. Languages like Mandarin or Swahili will be very important in tomorrow's world so a lot of schools are starting to offer them but they don't appeal to me very much. I guess I just really like our little IE family.
