Debt inevitably incurs costs: the interest and the usage fee. Borrowing means using someone else’s property as if it were my own. When the purpose of borrowing is achieved, or when the agreed time to return it arrives, it is returned to another person’s possession, and the borrowing cost is no longer incurred. Costs also serve as the basis for production and are the consideration for almost all debts, regardless of the borrowing purpose. The frightening aspect of debt is that it incurs costs and requires repayment of the principal. Originally, the principal was not mine. Thus, spending with other people’s money exposes you to significant risks, especially when you spend on perishable consumption that disappears after use. If you spend someone else’s money without differentiating between production costs and costs for extinction, you are on the fastest path to destruction. Therefore, luxury can ruin even the rich. - Joseph’s “just my thoughts”
In mathematics, a "recursive proposition" is a proposition whose true or false value is fed back into the proposition itself. For example, "I can never allow this to happen before I die!" is a recursive proposition. Unfortunately, the condition for proving that this is possible is that I die. The problem is that you are dead once, you can not be longer the person who gives permission. This phenomenon also occurs in the investment business. The most common example of this is an investment in stocks. This is a recursive proposition because if the price of a stock goes up and you sell it, the sales volume directly affects the price. Therefore, the number of shares (trading volume) is one of the most important factors to be considerable when investing in stocks. This property of recursive propositions is a good explanation for why the large trading of stock volumes is difficult to work. - Joseph’s “just my thoughts”
