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”
History professor Yuval Noah Harari said, "The most distinguishing feature between humans and other animals is the ability to believe not exist imagination." If you eat a banana exchanged with a bill from the chimpanzee, then the chimpanzee must be angry with you. The bill is just a thing to believe non-existent imagination each other in the human world, it's never important and meaningful for the chimpanzee. Unless the belief is to exchange the value, the money is just paper. This belief makes our social community. - Joseph's "just my thoughts"
