The most important rule in investing is not to lose your initial capital. Making money comes later. If you lose 50% of your principal, the loss rate is 50%, but to recover that principal, you need a 100% return. This is because the baseline of your return—the principal—has already been halved. Many people tend to think that if they’ve lost 50%, they only need a 50% return to break even. However, this is a misunderstanding of the starting point. In investing, the baseline is always the original principal. The principal after a loss is no longer the same; it’s already in the past. - Joseph’s “just my thoughts”
Google founder Sergey Brin, one day asked a great question. “What will happen if we give this service for free?” The result was, as we know well, “MONOPOLY”. Google gives employees 100,000 meals a day for free. This is because Google found that providing free meals is more profitable for the company. Initially, a payment system was introduced in the cafeteria. Soon, however, Google changed its mind when it saw the people waiting in line. Google learned the “opportunity cost”. Google's technology is excellent, but they realize it is not about making money. Fate changed when they discovered that the Business Model for that technology made money. - Joseph’s “just my thoughts”
