Thank you Scarlett and Bhanuka! It's a really good idea learning English through movies or TV series, I will do this for sure. I started reading in English some children's books and this is also helping me a lot. I appreciate your time spent to write these advices for me and I listen to every single advice that you gave me, thank you!

As Mr.Bluebottle said,Your article is very well written.I understood everything you said.When I searched the Internet most English courses indicates that you don't need to be perfect in grammar to speak the language well.They often say you have to practice phrases,listen and practice English.As Scarlett said Movies and TV series are good in learning English.If you try to learn American English.Try American Movies and TV series.And when you watch them try to use English subtitles if you can not understand what they are talking.But with subtitles you can understand what they are talking.So that way you will understand the movie or TV series in English.If you got a problem with words,try to use a dictionary.I think it is good to speak with someone in English.When you are keep talking to someone you will be able to speak English with any problem.You have a good vocabulary and I think that is enough for you to start talking.I also not good at speaking English.So I also joined here to find someone to practice English.Because I feel it is good to speak with someone than talking to myself.I think it doesn't matter that person is native English speaker or not.If they want to practice English with you that will be enough.So you don't have to worry about making mistakes.If both are learning,the mistakes are nothing to worry about.But you have to learn pronunciation from somewhere else.But you have someone to talk about what you learn.you have someone that you can practice with.That is the most important thing in language partnership.

I learnt english mainly through music/movies/series, when I had a better level, books, there's a lot of sources in english. Try find bands/movies/series you like in the english language, it helps with vocabulary, you see how the phrases are structured, and your listening, and consequently speaking also improve. Books are other really good way to learn a new language. If you can find a native to practice, nice. If you can't, write in english constantly or talk alone. I did it. I read you can try a lot of different methods when you're starting and then find which one you think it's working better. I tried duolingo when I started with german (I'm still a beginner), but I thought it was better Memrise. I can try it again after. See which points you have doubt, work on them. See what makes you improve faster, and what isn't working as well as you'd expected. Maybe you need change the sources after some time, maybe not. Other thing I did=when I wanted to read a book written in a foreigner-language that wasn't english, instead of looking for a translation in my mother tongue-portuguese, I searched an english translation. You can also search audiobooks and when you watch movies/series, put english subtitles, not the subtitles of your mother tongue (if you have some knowledge that allows you to understand the subtitles in english)
