What is the reason to learn English?

I'd like to learn English just to enjoy this wonderful language. Actually, I don't need speak English at work, because I'm working in a Spanish company, and all my clients and partners are Spanish, but I'd really like to become more fluent. I like watching movies in English because I think that you can enjoy the characters' performance in a better way, and I like to understad the lyrics of the music which I'm listening to.

I'd really like to become more fluent.  OR  I really want to become more fluent.

Me gustaría ...                                 OR  Tengo mucha ganas de ...

become more fluent = ¿legar a ser más fluido? (literalmente) Please correct my Spanish about how to say this.  What I wrote sounds strange.  Would you say:

llegar a hablar el idioma con fluidez (con soltura)?

Buen obra. Recuerde que en inglés, la capitalización es más común. Even adjectives get capitalized, not just the countries: he is Spanish, she speaks English, they are from America.
