We're fortunate to live in an Era where computers are prevalent. The best way to learn English (As the teach answered above) is to talk with someone who speaks the language and become friends with them. As for proper grammar, you can type with them over an IM such as Skype. I will be happy to help you learn English whenever I have time.

It's hard to give an unique answer because you didn't specify what is your current level and what exactly you want to focus on (conversation, or grammar, or writing, or ...?). First, you'll have to choose some kind of "formal" course that is organized into lessons; this will ensure that you pass through the necessary grammar and vocabulary in the proper order . This can be a book+cd that you study alone, or online lessons on italki, or perhaps you can go to an English course available in your town. Secondly, you can try watching movies or tv-shows that are spoken in English, using English(!) subtitles. Reading books is another thing that you can do. But you'll have to make sure that you pick books that are suitable for your current level .
