I am exhausted-2 Nov. 2010 I really made an all-out effort to prepare the seminar. I concentrated on my study from Saturday to today. Because of my poor English, it takes me more time to understand some easy defination. OMG, How can i make progress with limited time?! I miss my friends. I miss the life in Shanghai. Wow! Feel better. Keep on trying. Hope I can finish these mathematic problems before Thursday.
