I have been learning English since I am in primary school, but the truth was that I was not so good at listening. No matter how hardly I tried, I couldn't understand clearly which my English teachers or native speakers said. One day, I was surfing the Internet while an advertisement for English listening drew your attention. To my amaze, it was a website where recording of some well-known books were provided. When see the website, I fell in love it, which turned out to be that useful. Now I have made a progress in listening.
