I can't be the representive of all the Koreans who are learning English, but at least I can say that there is a difference in opinion about the logics between English and Korean thinking systems. By this reason, whatever I speak or write, it is based on Korean logic system so it sounds clumsy. We, who are learning English, reluctantly follow the way the native speakers do. Of course, I know it's not easy to do because we are not in an English-speaking environment. Use whatever they use. Repeat it. Make it as yours. That's what I've realized while learning English so far.

Someday, somehow, as long as we are learning the language, we'll be accustomed to the logic of that foreign language.

My mother language is Tagalog (Filipino) and my second language is English. I have tried learning French, Spanish, German and taking a look at Greek but I have chosen to devote myself to learning Korean and Japanese (which simplicity and logic I love and appreciate so much).

I love to look at foreign languages because, like you say, they have different logic systems. And I find that fact very interesting. That there are other ways to think of something is interesting to me. By learning a language, we develop another way of thinking. Maybe that's why the Czech proverb goes, "Learn a new language, get a new soul."

All the best to your learning English! :)
