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”
McDonald’s main menu featured barbecue, and the hamburger was one of 27 items. McDonald’s provided a system for customers to order directly, pick up a hamburger after a while, and serve the food on a plate rather than in a wrapper. When they faced stagnant business, they looked back at the cause and found that 80% of sales came from hamburgers, French fries, and beverages. It took a long time to reduce the menu and switch from plates to wrappers. The past holds back the present and the future. Poor success also involves the burdens of the past. - Joseph’s “just my thoughts”
