How to learn a second language well

I want to say a little about language learning. actually,after I chose japanese as my major,I used to be regret.I didn’t know how to learn a foreign language well.It is like that you drop into the sea,unfortunately,you can’t swim.But fortunately, I met a lot of good teachers.They help me to find 4 effective ways to learn japanese.
First， Spend the time.By far the most important factor is how much time you are immersed in the language. The more time you spend with the language, the faster you will learn. This means listening, reading, writing, speaking, and studying words and phrases. This does not mean sitting in class looking out the window, nor listening to other students who do not speak well, nor getting explanations in your own language about how the language works. This means spending time enjoyably connected to the language you are learning.
Second，Listen and read every day.Listen wherever you are on your MP3 player, this will create you a environment about what you are learning. Read what you are listening to. Listen to and read things that you like, things that you can mostly understand, or even partly understand. If you keep listening and reading you will get used to the language. One hour of listening or reading is more effective than many hours of class time. If you put your heart into.
Third，focus on words, phrases, grammars.Build up your vocabulary, you’ll need lots. Start to notice words and how they come together as phrases. Learn these words and phrases through your listening and reading. Read online, using online dictionaries, and make your own vocabulary lists for review, this would be helpful. Soon you will run into your new words and phrases elsewhere. Gradually you will be able to use them. Do not worry about how accurately you speak until you have accumulated a plenty of words through listening and reading.

Forth，take responsibility for your own learning.If you do not want to learn the language, you won’t. If you do want to learn the language, take control. Choose content of interest, that you want to listen to and read. Seek out the words and phrases that you need to understand your listening and reading. Do not wait for someone else to show you the language, nor to tell you what to do. Discover the language by yourself, like a child growing up. Talk when you feel like it. Write when you feel like it. A teacher cannot teach you to become fluent, but you can learn to become fluent if you want to.
Learning a foreign language is very difficult.And the point is that if you can find some ways to help you. now I found it.And you？
