I am a student of both Korean and Japanese. The grammar of both of these languages is pretty much identical. The Korean alphabet is much easier than Japanese, but the various levels of speach and address in Korean make it more challenging. So, in my opinion this makes Korean slightly more difficult than Japanese. The challenge with Japanese is the alphabet(s) and Kanji. Chinese is challenging because of the tonal intonations in the pronunciation as well as the characters that are needed to learn the written language. As far as grammar, Chinese is easier for Western speakers.

it's so hard to finish

 

finally Finally! i I finished my reading the Bbook that i have been holding on to for over the last a few montes months.
That's all It is written only in English.
I i should have done finished it already, but it still it was  is very hard for me.
Ffor me; even translating one or more a couple of sentences used to take so long time.
Aanyway, I i am so happy that I i came made it thruogh through all the volumn. (Or you can say, Anyway, I am so happy that I was able to finish the volumn/book.)
now it's just start. (I am not sure what you are trying to express here.)
honesly Honestly, saying I i have been kind of a lazy in doing something that is challenging needs hardship.
I i should change my attitude and need to uplift increase my intensity of focusing,
especially on studying and reading English.
아... 피곤해.갈길이 멀다.
Still, I i have yet so a long way to keep on going.
Mmaybe it would will take my whole lifetime, possilby remained without wrapping it up.
그래도 영어공부에 빠져있을때는 시간 가는줄 몰라요 ^^

 

Congratulations on finishing your first book written in English.  I have not been able to finish a book written in Korean yet.  I keep trying, but never finish.

 

I know it looks like there are a lot of mistakes in your entry, but I am just trying to make it more natural for Americans to understand.  Language study is a lifetime process, so don't give up.

First off, I want to let you know that your notebook entry is completely understandable by any English speaker, so good job.  I will just make a few corrections to make it more fluent.

 

Aaddicted to coffee.

Ever since I was in high school, I've been drinking coffee everyday.
and I'm sure that I'm addicted to coffee now and I can't stop to drinking it.
But everybody around me says it's not good for me, that I should try to stop and have gGreen tea instead of coffee, but I don't want to. And Also, I don't understand why do they say "Have gGreen tea instead of cCoffee". Green tea has also a lots of caffein like coffee.. haha.
I just like only it's taste and smell and I can feel happinessy and relaxed as only from drinking coffee.
I think there are lots of people who are same like me around the world, bBut I can't see find the those people like this arounde me.
Well hope I can find someone who is addicted to coffee soon. :P
