First of all, in sports, good health is the foundation of happiness to a great extent. For example, when you look in the mirror, you feel very stylish. Well, you are very happy. You can choose any exercise, as long as you like, try to reach the point where you can sweat, and if possible, you'd better find someone to exercise with. Then in terms of knowledge, I will find out what I am good at and like, and get in touch with some high-scoring movies, books and TV plays. Maybe later I will find that, uh, I like it very much. I seem to be more talented. For example, I didn't find myself interested in psychology until I watched the American drama Don't Lie to me, so I can find interesting things better by contacting new things through multiple channels. Then, as far as the mentality is concerned, try to be peaceful, and don't experience the violent emotional fluctuations of Dachuan, because science shows that strong emotions will consume a lot of energy, so try to keep yourself in a peaceful state. The other is the influence of various relationships. At least one intimate friend who can tell everything is his emotional sustenance. In front of this person, he can be himself without scruple, without wearing a mask, and judge whether some relationships are worth running and some emotions are worth paying. There is no need to force yourself to be a generalist. It's tiring and refreshing. Emmmm, you said you were going to take the postgraduate entrance examination, so you should have your own direction or something (I don't know much about it because I don't take the exam). Everyone around us is studying together. Just urge me to look at each other. Someone should remind you to make progress. As for the family, nothing can change, and the future is in our own hands. That's all I can think of. I hope it helps you.
