My uncle, a businessman his whole life, told me 40 pieces of wisdom about interpersonal relationships, invaluable. 1. A person who talks a lot is likely foolish. 2. Helping others is like slowly cultivating enemies; equal exchange is the long-term path to social interaction. 3. Don't complain to your mother; she can't help and won't sleep anyway. 4. A person who is petty and calculating is only suited for buying groceries, not for big things. 5. Once you're over 35, life becomes ten times more brutal. 6. When arguing with others, you're almost always the one who gets angry. 7. The more successful you become, the more distant relatives you'll have. 8. As long as there's no conflict of interest, you generally don't need to refute what others say. 9. The most childish thing an adult can do is confide in others; the more secrets you reveal, the more danger awaits you. 10. Don't concern yourself with other people's business; otherwise, you'll easily turn their troubles into your own. 11. When you're struggling financially, no one will ask if you're suffering; when you're eating meat, someone will always ask if it tastes good. 12. Any relationship should develop gradually. Don't try to explain everything right away; that's not sincerity, that's foolishness. 13. The best politeness is to mind your own business. When you warn a fool to be careful, you offend both the swindler and the fool. 14. Only those who support you financially truly value you. Those who genuinely want to help you never waste time with empty words. 15. Never worry about whether your attitude towards making money is good or bad. When you have no money, even your parents look down on you; when you have money, your words are the truth. 16. The best relationships aren't based on gifts, but on the "Mehrabian Law." 17. When you're old and lying in a hospital bed, you'll understand that the closest people in your life aren't blood relatives, but your money and your beliefs. 18. The bottom line for making money is the law, not morality. People with an overly strong sense of morality carry heavy psychological burdens; overly honest people rarely earn much money. 19. When a person is poor, they don't care about so-called face or feelings; instead, they must betray all the knowledge learned from the bottom. Only by completely separating from the bottom and becoming selfish can you climb up. ("Betrayal" should be "abandon" or "discard") 20. Be filial to your elderly parents; how you treat them now is how your children will treat you. 21. Don't do anything against your conscience; the older you get, the more afraid you become. 22. Don't live with relatives or parents for convenience; otherwise, you'll only reap dislike. 23. Money always flows to those who don't lack money, and love always flows to those who don't lack love. Energy is conserved; not lacking love and money indicates inner fulfillment, making it easier to achieve perfection. 24. There are only two kinds of people in the world: those who can never make up their minds, only dare to act in place, and are timid; and those who act immediately, constantly practicing and optimizing. (The word "action" should be "spinning around" or "hesitating") The outcomes of these two approaches are destined to be very different. 25. In fact, most of your friends are draining your money and energy; the fewer friends you have, the better your life will be. 26. Don't use favors and sweat to solve problems that can be solved with money. Don't use tears. 27. Don't rush to enjoy things that your abilities don't warrant, let alone pursue a life that doesn't match your abilities. 28. The first core of a family is always finances, not emotions. Read "establishing a career and starting a family" and "being a good wife and mother" backwards twice, and you'll understand everything. 29. If a stranger bullies you, let it go; they'll be a stranger again. If an acquaintance bullies you, fight back immediately; once you do, it will happen countless times. 30. The magic weapons to change your destiny: giving gifts, gratitude, obedience, sharing money, and going along with the crowd. 31. When riding in someone else's car, get out as quietly as possible, otherwise you'll easily be disliked. 32. You can visit shops owned by acquaintances less often, but you can't never go. 33. Never treat accomplishments built on trust as something to brag about. 34. The higher the family pension, the more harmonious the life. 35. The best education is: don't expose, but stay away, quietly eliminate. Adults make choices, not educate others, because shaping a person takes time and experience. Kindness and truth should be given to people; don't force others to change. Learning to let go is the clarity of adulthood. 36. Don't get red in the face over winning or losing. 37. Don't let important people worry about things that aren't important. 38. The rule of the game is that once someone leaves, the tea cools; don't ask why. 39. People who embarrass you are 100% looking down on you, not because they have low emotional intelligence. 40. Being able to speak appropriately to different people isn't hypocrisy, it's a skill.
