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”
When you bleed, the blood comes into contact with the air, it changes from a liquid to a jelly, and then from a jelly to a solid scab. This inherent property of a substance is called its "physical property". If the properties of blood do not change from liquid to jelly and then to solid, people will die from excessive bleeding to death. Thus, physical properties are quite important to our life phenomena. The properties are almost everything in the business of food and chemical products. We can do our business although without an understanding of the properties. But if we cannot understand, or do overlook them, even a coffee shop can't expect to win the competition. So start by understanding the properties. - Joseph’s “just my thoughts”
