Listening Portfolio

I like listening both English and my first language, but I'm not good at listening English. I think listening is a quite important skill of learning not only English but also any other languages.
I like both listening to in Korean, and English, but still I prefer listening in Korean to listening in English. When I talk with other people in English, I always misunderstand what people said and then I say them "pardon?"
I'm trying to avoid watching Korean subtitles when I'm watching English movies. If a movie has English subtitle, I use it only first time. And sometimes I listen to a radio. I think the best way to improve listening skill is watching English TV programme or movies.
