Because it’s widely use. And I want to know more and understand people better around the world.

I want to learn english becouse I want to feel free and not depend on anyone. This language is universal and this language is spoken all over the world. I think so.

Well... I don't want to learn English :-). It's something like a necessary evil, everybody use it and it seems it's the language you can use everywhere you go without learning the language of each country. Sure, that's very comfortable, however, I think you know the country and the life in it better if you know those people's mother language.
