Time flies, I often think of Confucius' famous saying: "Stand at thirty, be confused at forty, know your destiny at fifty, and be obedient at sixty." This sentence contains too much philosophy of life, which is the coordinate for China people to locate their life time.

I was curious about the outside world when I was a child. I am curious about everything, but I can't find the answer. Everything needs the help of others. This is a kind of external dependence. What teachers say, what TV, movies and books say, are authoritative and the source of knowledge. I remember when I was a child, the arguments between children were often based on what the book said, which was a strict sword on the square and the gold standard.

When you reach the age of 30, you can decide your own life path and start your career. Curiosity has been greatly weakened, and we have a general grasp of the world. In fact, we don't need too much curiosity and less dependence on the outside world. But not to the point of "no feeling", the perception of the world is still thorough.

"forty without confusion" means that you really have a complete understanding of the outside world and a rudiment of life. There is nothing to be curious about. What I don't know is because I'm not in that line of work, so there's no need to know. If you feel "forty without getting it", it is because there is no opportunity and no good platform. But people at this stage often feel anxious, and they have reached the peak of their lives. If you don't act, you won't have a chance, and your age savings are running out.

Every time I think about the passage of time, the passage of time, I am half afraid and half uneasy, so I have to worry about getting angry. If you can live to 500 years old, these anxieties will be much less.
