Phil,
Thanks for replying. I think it is a lot harder to choose which language to learn if you want to live and work in Europe, clearly in the Americas, Spanish is the best language to learn but in Europe there are so many to choose from! I don't see the point in guessing which language would be most useful.
I am not in that 21% as I can speak another language fluently but I wouldn't think of learning a new language without having any idea which would be more useful in terms of getting a job. I may be damaging my employment prospects by not doing this but with the time spent learning the language I could do other things to boost my employment prospects...
Louis.
