If you are determined to learn English you should find a native or fluent speaker for conversation. You can have a free course if you can find someone who is willing to be your language exchange partner.(There are many English native speakers around who could be interested to learn your language or culture.)
Then, you should agree on a certain schedule on when to exchange calls. It's also important that you use the same textbook.
