Two thoughts

I have two totally different thoughts now. One is that I am in the great improvement of English now. I am in The States, and I am trying to be with people who cannot speak English. I think and I know that's the best way to study English. In the sense I am really satisfied.
However, I also have another thought. That occures when I cannot understand what people are saying. i wonder whether I would be able to understand all of them one year later. It bothers me a lot. Of course I hope so, but now, it seems to be so difficult.
Anyway, now even classes don't start yet. Thinking too much is bad. Take it easy, take it easy...
