Now it’s already passed 00:00 am, so it is Monday now. The spring semester 2011 has begun and it will be a busy semester. I will study four courses, probability theory, theoretical statistics, applied statistics methods(generalized linear method) and machine learning. I should change my attitude for taking classes. In the past, I just took classes as duties. Now I think it is wrong. I should take them as the materials that I myself want to learn for the fundations of my academic life and the following research. I should regard the instructors as secondary and myself as the cardinal factor. Fighting!
