What happened in these three days

I just arrived to America at 21 in the morning, actually before I came I was not feel excited really. But when I just get off from the airplane, I know something are different, there's all the different kinds of people everywhere, from now I become to be the foreigner. I need to speak totally different language everyday, there will have a lot of problem in here,  about studying,  shopping, but there also will have many exciting thing, such like I can meet a lot of totally different people everyday, because it's a new place is fulled of strange people.
I feel like I have lots of knowledge to catch up. The vocabulary, the grammar.
I think I will learn, see, feel a lot of amazing stuff at here.
Next week I will start to work out, and swim, I already ran since yesterday.
