I have read a book named The Present. I have been learning a lot from the book. I will talk you what the book said after I finish it. Now I would like to mention about what I did after I read part of it. Today, I gave up the former habits. For instance, one is I always could not concentrate on classes. Another is I always spent a lot of time doing my homework, and reviewing even it was easy because I could not pay attention to deliberate about what they said. The other is I understand importance of preview but I had never done it except I know it will have the quiz before the class. However, I did the new and good habits today. I feel so wonderful because I have a sense of success. I made substantial changes. I hope I can persevere unremittingly.
