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”
White hair is referred to as “gray streaks of hair” when it is sparse on black hair. However, when there is more white hair, it is called “white hair.” Quantity is an essential criterion for distinguishing meaning. When analyzing certain phenomena, quantity significantly influences definitions and meaning; however, it can also overlook other important aspects. Therefore, the meaning of “quantity” should always be considered carefully. - Joseph’s “just my thoughts”
