When investing in a market where asset trading is ongoing, persistent, and prices are constantly fluctuating, the most important factor is the perception and attitude toward “time.” Here, time refers to a defined “period,” a concept that encompasses the “past,” “present,” and “future.” Knowing the future can make us wealthy. All we know is the “past,” but in reality, even the past is often not fully understood. That is, we must admit we lack complete knowledge about the past, present, or future. In this state, we must conduct business and invest. The attitude toward business and investing is to focus on judging the “trend” by applying the concepts of differential and integral calculus simultaneously. Differential weather (e.g., morning and afternoon of a day) is easy to predict, but long-term future weather cannot be forecasted even by supercomputers.

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”
