Salary isn’t just ‘my money.’ It’s money that should be spent considering yourself today, your future self in 10 years, and your future self in 20 years—that is, your future self together. Therefore, my current income is always, in a way, public money. We need to get approval from our future self before spending now. A bright future is only guaranteed if the future self agrees to the spending. It’s inconvenient to spend other people’s money on your own terms, and thinking of your own money the same way you see others’ cherished money will help you develop good habits for the future. I don’t have an exclusive claim to my own money, as if there’s no such thing as my own air in this world. - Joseph’s “just my thoughts”
British anthropologist Robin Dunbar was certain that primate cerebral neocortical capacity determines the number of social relations. He definitively established the limit of human relationships at 100 to 230 people. The average value of 150 people is known as Dunbar's number. In the world of chimpanzees, 30 is the absolute maximum. However, fewer than 12 people in the world can sympathize with me. My best friend is now reduced to 3 or 4. The relationship quantity decreases to the square root value and increases to the square value. Three or four of my best friends will eventually connect with people from all over the world. This is the same principle as when one or two virus-infected people infect the world. Focus on your best friend. - Joseph’s “just my thoughts”
