What's wrong with this society now, you have to find it yourself. No one will tell you. People only like to see you ugly, but they don't like to see you.

Part of your idea is right. If you have any problems, you should find them yourself, mainly by yourself. But as a person, time, cognition and energy are limited, and you can't achieve 100%. This is an objective reality. At this point, you need external feedback to point out your problems.

In this society, especially in China, people are under great pressure to survive. To survive in society, people need the recognition and affirmation of others. Everyone has his own specific situation, which is different. How does a person know his position in this society and whether he is living well? Only by comparing with others can he know. Virtually, a kind of competition is formed. Just like you said: people only like to see you ugly, but they don't like to see you hello. This is just a superficial phenomenon. Everyone has this idea, not only others, but also you, me and everyone. Just imagine, a person, thinking like this all day, bursting with negative emotions, how can he still have time and energy to work and study, which is harmless. This idea should be controlled and eliminated. I have to admit this objective idea of human beings and face it frankly. We should objectively and comprehensively understand and evaluate ourselves and the world, base ourselves on reality, and strive to change and strengthen ourselves, so as to survive better and have stronger adaptability. Be a positive example and push people to be good. And if you complain all day and do nothing, you will get nothing. Compare the two. What to do is clear at a glance. Go and act!
