Learning another language is easy but to be perfect is difficult.

For me, the most important thing is the basic. We should study the basic of language. I think that the basic of studying foreign languae is grammar. In my case, I was studying English and Japanese grammar in Korean.

Then I try to remember usefull sentences reading and writing. Reading aloud and writing by hand involve a number of senses. I like to read a dictionary to understand using of words.

Repeat and test it until remember perfectly. repeatation and exame is effective.
I try to never miss and repeat my mistake. So I don't mind to study many progress.
Even if it take the time, I don't be so impatient. Ultimately, it can more save time. I took 5-10 hours to study everyday when I studied and Japanese language during 1-2 year. It helps me to speak and write Japanese without difficulty. Now I am also studying English 5hours a day. I will continue this way until August in this year. And then I will practise and enjoy English data and culture.
I want to speak my opinion and have a brainstorming. I try to think in English.
That is the reason that I need a teacher.

In my free time, I am listening a lot movies, lectures, news to check my linguistic ability and find my roll models.

Learning another language is easy, but to be perfect is difficult.

For me, the most important things are the basics. We should study the basics of language. I think that part of the basics of studying foreign language is grammar. In my case, I was studying English and Japanese grammar in Korean.

Then I try to remember useful sentences by reading and writing them. Reading aloud and writing by hand involves a number of senses. I like to read a dictionary to understand how to use words.

Then I test myself and repeat it until I can remember them perfectly. I think repetition and exams are effective.
I try to never repeat any of my mistakes. I don't mind studying a long time to progress.
Even if it takes less time than I thought I still try not to be impatient. Ultimately, this can more save time. During my first two years of studying Japanese I would study for 5 to 10 hours a day. It helped me to be able to speak and write Japanese without difficulty. Now I am also studying English 5 hours a day. I will continue this way until August of this year. Then I will practice and enjoy English culture.
When I brainstorm and want to give my opinion I try to think in English.
That is the reason that I need a teacher.

does this sound natural?

I think this was a good essay. Most of your vocabulary was correct. You were only missing a few words. I recommend if you post another long message you should put it on Lang-8. They have editing tools that will make it easier to see the changes I made. You can find my profile on that site. My username is Ukeath. I look forward to reading more of your posts.
