One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - Joseph’s “just my thoughts”
The small good works resemble the great evil, and the large good works resemble the insentience. The words that Confucius said to Jaro. It's better to give even a small good, but rather it can be evil, and cruel behavior is so bitter, but as a result, it becomes often a good thing. The executive is not a person who does good deeds, but a very fatiguing person who sometimes needs to exclude emotions and make profits because it is a good deed not to go bankrupt. - Joseph’s “just my thoughts”
