Well, I believe that you have to study hard. Try to read and listen to so much. In the beginning you'd like to give up and you can believe that you'll never get to learn English, It will take patience and persistence. Good luck!

I think it will help if you will listen to english songs or watch english series/movies. In this way, you can mimic them and practice your english. Aside from this, you can enroll in an english language school to help you with the grammar and right pronunciation. Always practice, practice, practice. That is the key. :)
