Why do people's thoughts change in stages?

People's thoughts are mainly related to personality, environment, knowledge, circle, family style, parents, beliefs and so on. Life experience in youth, though tortuous, is actually sharpening one's beard and edge. When young and energetic or talking to people, it is caused by careless words, which causes certain harm.

But when people reach middle age, they can see more clearly through three views. It is also because people have some freedom in their careers, know how to be sober and reflect on themselves, and often take notes. They gradually became interested in faith and became a compulsory course. They are conscientious to their family members and relatives, especially to their parents and those who have helped them. When they are mature, their husbands and wives live in harmony.

In the year of sixty, I gradually paid silently and cared more about my relatives and friends. I look down on the world, too.

This is the life tetralogy, from birth to adolescence, middle age to old age death, which also shows that the four seasons of all things have not changed, but the mind is changing with the surrounding environment, from stubbornness to persistence, to letting go, to speaking simply, to looking in the mirror, to looking in the mirror, to a certain extent, the persistence of the mind and mind, the cherish and let go of fate, and the change of material and quality.
