This truth is the same as learning. The higher the education level, the greater the possibility of higher income, but it does not mean that the higher the education level, the higher the income, and the lower the education level. Nothing is absolute.
Whether it is mature or not is still related to a person's mind and whether he loves you or not. I once talked about a boyfriend who is seven years older than me. I thought he would be very mature, but later I found him particularly naive and irresponsible. He only talks sweet words and sugar-coated shells. Maybe he doesn't like them enough. Fortunately, he broke up later and the wrong person left as soon as possible.
I have a distant relative who is married and has two children, but he idles around all day and his business is not good. He lives on the money he receives every day, but he has no savings at all.
He can't solve anything when something big happens. He doesn't care about his family. He eats and drinks every day and often goes out to eat with his so-called brother. It seems that he is still rich. However, paper can't cover the fire. In the end, he paid the price for his childish behavior.
After this incident, he knew that life was not easy, and he finally really grew up. Therefore, whether a person is mature or not has something to do with age and little to do with experience. The road you have traveled has finally formed you.
Maturity and age are not necessarily in direct proportion, there must be a connection, but there is no necessary connection, because everyone's maturity dimension may be different. Many things have different interpretations at different stages of life. This is not only a question of age, but also a question of experience endowed by age.
