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”
Humans, among Earth’s creatures, have the largest whites in their eyes, making it easy to convey the movement of the eyes outward. For this reason, eyes communicate a great deal to others. With just a glance, it’s easy for humans to intuitively grasp a person’s emotions. Most herbivorous animals have horizontally shaped pupils, an evolutionary adaptation that allows them to detect approaching predators even while they bow down to graze. The eye serves as an emotional and social organ. - Joseph’s “just my thoughts”
