Do not make mistakes, as the cost of rectifying them afterwards is high.

From the day you do something wrong, everyone will cut ties with you. Everyone will pretend they don't know you, avoiding you like a plague.

Take the movie The Three Captains, for example. Once you do something wrong, everyone immediately severs all ties with you. It's not that your wife is going to remarry or your daughter won't acknowledge you—it's simply reality forcing their hand. What else can they do? If they don't, your daughter will be looked down upon at school and will never be able to hold her head up. Do you want to ruin her life? No? Then get a divorce proactively, take responsibility for your actions, and don't drag others down with you. All your friends around you—the people who used to call you "Captain Cheng"—will distance themselves out of fear of getting implicated. Sure, you'll make new friends, but what kind of friends? People who have no future, marginalized drifters. From then on, these losers will become your entire world.

Don't make mistakes. There's no such thing as a secret online; every move you make is being watched.

People, especially young people, have a major flaw: they take pride in making mistakes. The more you're told not to do something, the more you want to try it. That's not individuality—that's the root cause of the regret you'll face later.

Those who think they're being unique will end up looking like Zhang Yi's character—a down-and-out middle-aged man in a movie. It's only those who seem unremarkable who can live up to Li Chen's portrayal: successful in their career and happy in their family by middle age.

That's not called lacking personality. That's called being mature. That's called having reverence. That's called knowing the difference between what matters and what doesn't.
