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”
Famous for his book "The Gun, the Germs and Steel," the great scholar "Jared Diamond" speaks 13 foreign languages. Once he made the wrong decision to change his job. He wanted to leave the field of science behind and become a "simultaneous interpreter." In the United States, however, speaking 13 languages seemed competitive, but being able to speak many languages in other parts of the world could not be competitive. Before doing a preferred occupation or doing something better than others, you should calmly be able to figure out your field of action first. - Joseph’s "just my thoughts"
