There is no standard answer to the question of what happiness is. Happiness is just a personal feeling. Whether you are poor or rich; Whether you are in a high position or a grass farmer; Whether you are in your homeland or wandering in a foreign land, as long as you feel happy, you are happy. The French writer Flaubert once said: stupidity, selfishness, and good health are the three elements of happiness. But the main thing is stupidity, without stupidity, there will be no happiness. The selfishness and good health mentioned here can be understood by everyone, so there is no need to repeat it. Let's focus on "stupidity". To understand Flaubert's "stupidity" is to be wise and foolish, to have a deep understanding of human nature, and to pretend to be indifferent to the facts that cannot be changed. There are some things that are not explained thoroughly, pure in heart and few desires, not vain, not extravagant, not greedy. Be a low-key person and disguise yourself as a weakling.
On the other hand, if you are calculating and anxious about the uncertainty of the future. He is full of resentment and injustice about things that he is not used to seeing but cannot change. Inside, it's obviously empty, but it packages itself as a very powerful appearance. Well, happiness will never belong to you.
It can be seen that you will only have enough happiness if you are "stupid" enough.
