It's difficult to be two things at the same time, especially when the two things are at the opposite of the spectrum, like the East(Korea) and the West(America).
But then again, if you can somehow integrate only good things from both sides, then you can thrive both in America and in Korea, too. I just wish many Korean-Americans (or any immigrant from foreign country for that matter) can successfully pull that off. They can be bridges connecting each and every country around the world!
