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”
In philosophy, the term ‘concept’ denotes an idea formed by extracting and synthesizing common elements from an object or phenomenon. If you lack strength, it’s better to focus; however, if you don’t understand the concept, you can’t. Without knowledge of the concept, you remain unaware of the boundaries and classifications, making it difficult to discard what’s useless or select what you genuinely need. Understanding the core idea means grasping a concept that remains constant even when circumstances and environments shift. - Joseph’s “just my thoughts”
