Before the age of 30, one should strive to add,
Try as much as possible, experience, and make mistakes.
Explore the splendor of the world and experience different lives.
Make friends from different fields, and listen to voices from various areas.
After 30, one should begin to subtract,
Think as much as possible, summarize, and settle down.
Reflect on the meaning of life and consider one’s own value.
Reduce ineffective socializing, and stay away from people who drain you. Focus on your own field.
Of course, 30 is not a fixed boundary,
It's just an average age that I believe is suitable for most people.
If you haven't experienced enough, even at 60, you should continue to add.
If you have enough experience, even at 18, you can start to subtract.
Physical age only affects a person's body,
Physical age does not affect a person's mental age.
In this era, there is a phenomenon where:
A child in their teens may have a more mature mindset than some people in their forties or fifties.
This is not surprising at all. Because the educational environment has changed, and educational resources have increased.
But it is merely mental maturity; many still lack experience.
It's a bit like a giant baby in thought but a dwarf in action.
In ancient times, children in their teens could already hold official positions and go to war.
Emperor Zhao of Han ascended the throne at 8 and married the empress at 12.
Huo Qubing became a cavalry commander at 17, leading 800 cavalry against the Xiongnu.
He Shen became an official at 18, serving as a light chariot commander.
In 101, one became the commander of the Red Fourth Army at 23.
Many people in ancient times did not have the opportunity to study, yet they could still achieve great things.
Because they were driven by circumstances to move forward, rather than being pushed forward by books.
So whether a person matures early or not does not depend on ancient or modern times,
It depends on whether it’s a time of peace or a time of war.
Now many people study in school until they are over 30; is this reasonable?
Anyway, I think it is extremely unreasonable. People do not need to read that many books.
In times of peace, people become numb, while in times of war, people become crazy.
Being born in a time of peace is a kind of luck, but also a kind of misfortune.
Cherish peace, occasionally be crazy, and stay awake.
