So it has been a really really really hectic semester. Going to MIT everyday definitely trains my physical and mental strength. Now I can sprint through the whole MIT infinite corridor in 2 minutes with my schoolbag and every thing. and I become very experienced in chionging from my class in science center to the bus. should claim some PE credit for that.

It has not been easy. There were setbacks and tears and don't-know-what-I-am-doing. But in the end I did well.

For one of the classes I did really well, partly because I didn't to well for my first midterm. I was so upset at that time and was crying so hard, but now that little setback has forced me to learn the subject more thoroughly. Sometimes setbacks are there to help us to learn better, isn't it?

I feel a little sad that some friends are leaving because they are graduating. Some of them have hugged me so tightly when I was upset, and cheered me on. I am really grateful to them. I wish them all the best, and hope to see them some point in the future.

And I am going to Germany this Saturday, for three months of research. I am very nervous about that now.
