I have to admit...

It was a mistake to quit PhD... When I went back to Duke a few days ago, I again strongly felt sorry about leaving the campus and I envy the people walking around. The sun was shining and everything looked energetic on campus. I miss that feeling a lot. Although I enjoy my job and I was scared by prelim, I just can't help missing school. I felt younger on campus. I hope I can go back to school, no matter studying or working, sometime in the future.
