I use my target language everywhere, especially when I read books, meet with my professors, and take notes.

Or "write down notes."
"Take notes" = when you're in a class and you write down what the professor is saying
"Write down notes" = more general; like maybe you want to make sure you don't forget an appointment or something

Especially, when I read a book, have a meeting with professors, and making a note.

This should be combined with the previous sentence.

If I don't have time to practice the language, I will make it before sleeping, itwhich really helps me.

Not sure what you mean here by "make it before sleeping."

If I had studied English with guys who already knoew English, then I would have learned thise language faster.

So iImmersion is neededcessary to learn a language for everyone.

Best not to start sentences with "so"

Where I live, there is a popular phrase: "yYou make friends with four millionaires, you will become the fifth, you ar. You make friends with four robbers, you will become fifth, c. Choose the right environment."

:D

I know that immersion and the right environment can help me to goal my task, wachieve my goal. While I don't have enough money forto traveling to a foreign country but, I can make an artificial environment by using Youtube, Soundcloud, Omegle, and Langcorrect.
