Learning English

He everyone.
Today I decided to resume my English studying. My friend gave me some advice: at first - If I want to learn English and want to speak, I will have to practice hear listening to English speech and for better understanding I must watch English serials without subtitles, only sound.
Secondly - I will have to learn grammar because it's necessary for speaking and taking examinations.
And in the third - Regular topics can be useful for my thinking, I must try to think in English. Now I think in Russian and translate sentences to English in my mind. It's very slow and not good. So I will write some topics every 2-3 day, maybe more often.

What do you think about this advice? Is this really useful ? I will be so glad if you correct my text.

Thanks

Very well written.  I agree with the advice. Another useful practice is to read out loud.. speaking  the words to yourself.  It will help you recognize the words when you hear them.  You must practice making the SOUNDS of the english language as well as the words.  Good luck. -Sven
