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 probably may use less than 5% of the function of a human brain in their intention. If easily these senses of pleasure, hallucination, or pain can be used or our intentions control memory circuits, human beings will be destroyed themselves. It’s very great luck to be uncontrollable at our discretion. - Joseph’s “just my thoughts"
