Because young people nowadays think too much and worry too much. Some people still have abnormal perfectionism. Obviously, some minor shortcomings are normal, but it is better to belittle yourself and sigh. Some people know that in the current task, only learning can best reflect self-worth. But I chose to do something to relax myself. The ambivalence of students also reflects the tendency of modern people to do things in their student days: "no learning and no skills", immersed in their own world and not recognized by their environment. There is always a rule in people's hearts, which must conform to the general environment. Beyond this invisible chain, everything will be unacceptable and criticized. Even if outsiders don't notice the psychology of these people, those parties will suffer and deny themselves, but they can't get on the right track. Unconsciously, people put on an absolutely correct shackle for themselves, unable to cross the spiritual and language barriers. In this way, you will never enjoy the happiness and satisfaction of the present and self-choice, but always have bad feelings and think about the past. After all, if you don't follow the mainstream thinking and are not understood, you have a burden in your heart. Another point may also be related to the fact that most of the younger generation are only children. There is no mutual support between families, but more love. You need to take on more responsibilities, enter the society earlier, take on more responsibilities and mature quickly, so it seems that you are mature.
