My reasons.

I want to learn English because I believe that this language is usefull useful. I can't (can, maybe?) find a lot of information about many topics in this language. Also, I think that English is beatufull beautiful because it sounds good (nice, maybe?). A big part of my favorite bands composes music in English.
In comparison with Compared to other languages, English is easy. I think that English is similar to Tarzan's language. Spanish, Portuguese or French require you to change verbs when you change the subject of the sentence, (example: yo quiero, tu quieres, el quiere, nosotros queremos) but in English it is not necessary (example: I want, you want, we want).
The final reason is that I love to know other cultures and English allows me to achieve that goal.
