At least that being one of the main reasons? What was it and were you successful with it?
Have you learned a language for the sake of its exoticism?
In countries like Spain learning a foreign language, no matter the one you choose, is considered exotic. So I did learn ( in part) an exotic language, English.
Learning English also has the practical upshot of enabling you to converse with someone other than uneducated primitives.
In the whole world? are you sure? and doesnt it actually depend on who the learner is?
