I really know some classmates who went to Tsinghua Peking University. Although I envy them, I still have a certain reputation of self-knowledge. I also want to observe their lives through study, and I do find that they are basically the same as most of my classmates. More serious than them. I've seen them. I have countless memories of those who worked harder than them, and I have witnessed and felt those who were smarter than them. But in the end, they didn't get the results of these students who were admitted to Tsinghua Peking University. Over time, I did find some different places, although they were so inconspicuous. First, they are humble. They are never complacent about their achievements. They always listen carefully like children, and sometimes they are confused. They always feel that they are still far behind. On the contrary, sometimes I look so cocky because I can do a math problem and others can't. Later, when I wanted to understand them, I realized that my behavior was so despicable and ridiculous. Because their ideals are never the same as mine, they are the sea, and all I need is an occasional glimpse. Alas, they are too polite to others. Secondly, they are always calm and calm. I have seen too many people cry because of an unexpected failure in an exam. In their eyes, failure is absolutely not allowed. It seems that a failure is doomed to face the abyss. Then their punishment for themselves is to continue to work hard, and their comfort is to study hard and then do well in the next exam. If they still fail in the exam, it will be over and their mentality will explode.
