I'm looking for a correct way to learn English

I love English. I've studied it from the 6th grade of the primary school. It has been more than ten years already. But I'm still not a good English speaker. I don't know how to express a lot of things. There were are many people who were are studying Chinese on TV. They could can say Chinese fluently after studying it just for several months. That's amazing! I always think that I am stupid. The only one thing I'm proud of myself for that is my pronunciation. I say speak Ameican English. Please forgive my poor English. Originally, I wanted to express many things but I don't know how to do it. I'd just like to know how to study English. Thank you.^_^
