How Do I learn English language?

I have already have the base knowledge, but still make a lot of mistakes. I can speak freely communicate  in English free, but my purpose is to speak communicate without mistakes.
I spend almost 2 hours a day to study English language.
I read, listen, watch something interesting to me every day. Try to understand all, but if I don't understand some words I look check it in dictionary and learn it.
I heard one method of learning some days ago.
According to this method, you listen to one dialog as many times as possible one dialog and only when you until you remember almost all, you start to pronounce it in loud. You try to repeat the intonation you heard on the recording.
It is look like children learning language.
