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”
In the 2009 Korean film ‘Castaway on the Moon,’ a character states, “Desire makes humans smarter.” This reflects the protagonist’s ingenuity in creating useful tools from discarded items to survive on a deserted island. While knowledge enhances human understanding, it is desire that turns that knowledge into practical applications. Maslow was among the first to focus on this concept of desire in social science research. Understanding and addressing desires essentially means understanding humanity. - Joseph’s “just my thoughts”
