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”
Macroscopic and microscopic perspectives sometimes reveal contradictions or conflicts of logic . We must consider the variable of time when forming our thoughts and judgments, because in many cases what is considered right macroscopically may not be appropriate microscopically . In stock investing , stocks deemed correct from a long-term view are often seen as poorly chosen from a short-term perspective . Our values and judgments are sometimes praised and at other times criticized over a certain period. It seems like an innocent prank over time. - Joseph’s “just my thoughts”
