Practice... nothing will help you like practicing the language with other speakers of English. Practice is perfect.

Practice speaking! You will never get better if you don't practice. Try keeping a diary in English and reading the words you write out loud. Watch British or American movies and TV shows with the subtitles on and try to pick out the words you know. Listen to music in English. Try reading children's books and gradually work up to harder books. Good luck! I've been told that English is a hard language to learn. If you need help or practice, let me know!
