Rejection Cost. From the perspective that my profit is someone else’s loss, and someone else’s profit is my loss, the fact that I have to reject an opportunity to make money for my circumstances is a loss for me and an act of giving someone else a profit. In other words, my added value is not determined solely by productivity but also by the marginal utility generated by the law of supply and demand. Therefore, my labor price should reflect the value that I have given up—the profit I could have gained. If the rejection cost is not included in my profit, I will be at a loss to that extent. Failing to account for rejection costs in production expenses is not wise, but foolish, because it risks my survival. There is no absolute value in this world. All economic values are relative. - 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”
