What do you think of happiness?

As the saying goes, man struggles upwards and water flows downwards. Man is small but great in front of nature. Happy-go-lucky understanding of me is the people and things we meet in life. First of all, we must maintain a stable and calm state of mind. We all hope that we have a good human and natural environment that suits us. We all have subjective initiative. First, we accept it, and then we try to change it. In the case that people cannot change, we should change ourselves, change our mentality or change our environment. The so-called "environment is born of mind" depends on how you think and do it, but it is wise to understand the word "let nature take its course" correctly. Whenever it happens, my heart will be at ease first, and then I will have wisdom. Wisdom is born.
