Exept my language,I would like to learn English

Other language that I would like to learn except my native language is English. Since I was young kid I was interesting how to learn speaking English well. I had tried before, but I did not have success learning English. At the end after I have moved to the United States in 2006 I have no choice. Since now I am living here in the U.S. I must need to know speaking and writing in English because other wise I would have difficulties for my life. English is not important just to speak and understand people, but is more than that. If you know to speak English well you will not have any problem finding a job or traveling around the world. English language has become the first spoken language. In nowadays for many position even in different countries they require English language. So for me is necessary learning English because I want to study and become successful in my new life here. So far I am not very well with English, but fortunately by going to school ad speaking to other people I will improve my English skills. If I can keep going to school for next couple of years definitively I would be able to communicate and speak English fluently.
