Everyone likes to compare things. When I was a child, parents liked to compare their children with those in the neighborhood. The children in the neighborhood can wash clothes, get good grades and are more unhappy than my parents. Teachers also like to compare which students have good academic performance and why some people can learn well, so you are an idiot. This comparison will make students feel that they are useless and can't learn the most basic learning well. You will love beauty more, why others can buy all kinds of clothes when they have money, run around and buy more, better and more expensive things, why others are so beautiful, and so on.

It is not a happy thing to compare yourself or be compared by others since childhood, but everyone is unique. Just be ourselves. You envy others, and others may envy you. Comparison has stolen too much happiness from us.
