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”
On the highway, I saw a warning saying “Half of the death accidents were not wearing seat belts”. This means, “Even if you wear a seat belt, half die.” “Safety” is emphasized by saying “50% reduction in mortality when wearing seat belts”. In the former, 'probability' was noted, and in the latter, the effect of 'reduction' was emphasized. - Joseph’s “just my thoughts”
