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”
You probably suspect that your decisions are reasonably based on your judgment. However, human decisions are made according to the rules and structures at that time. By changing the decision structure and regulations, humans make different decisions under the same conditions. If you make a mistake, you don't have to regret or blame yourself for making the wrong decision. But, if you fail to judge the regulations and structure of the decision, then you must reflect on the mistake. This is to prevent repeated mistakes. - Joseph’s “just my thoughts”
