How to learn English quickly?

Hi! Do you know any method to learn english quickly and correctly? It is every hard to learn English because the grammar of Japanese language and English language is different. In my opinion, the following steps can help new learners get rid of worry about learning foreign language:

Focusing on grammar, learning new vocabulary everyday, praticing speaking and listening, trying to talk to foreigners in English. And try to pratice with Pronounciation.

Practicing everyday is the key.
You might also want to immerse yourself in the English-speaking cultures, by watching television, etc. in English. Pick a popular TV show and watch it. It'll teach you a lot about the culture, the way natives speak, correct pronunciation, grammar, etc. It also gives you new topics to talk about when you are talking to your conversation partner in English!

Phonics.

THE biggest reason that Japanese people have trouble with learning the English language is because they have little to no experience with learning phonics. Formal study is needed to understand things like dipthongs, double vowels etc... but this can be done by listening to English music WITHOUT looking at the lyrics and just trying to hear the rhythm of the words and how they are spoken. Eventually you should try to sing along.

I really think English radio (news radio if your English is advanced enough) is a wonderful way to improve your comprehension. Radio hosts for news broadcasts generally have crystal clear speaking voices and it can really help. I agree with everyone else who's posted as well:

Kiyo90's everyday practice advice is essential because it helps the brain become accustomed to using the language. Do you ever hear stories about people who could speak a language well at some point, but now they can't? Lack of daily practice plays a big part in that.

Crustpunker's phonics advice is great too, because the phonics differ from language to language. It can make a huge difference in how naturally you speak, and even to what extent you comprehend English.

Oh yeah. I have one more recommendation. Watch Sesame Street!! It sounds like a joke, but I'm serious. I even tell my advanced students to try it sometimes. Believe it or not, even though it's a kid's show...it's made for native-speaking children. Give it try, you might find some of it useful...dare I say...entertaining?

Good luck
