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”
The reorientation and expansion of a business should be planned and decided in terms of customer synergies, not company synergies. It may be more successful to offer a customer who buys apple jam an extra slice of bread to spread it on than to provide a customer who buys apple jam an extra jar of peach jam. It's easier for the jam seller to give away an extra jar of jam, but for the customer, the bread is more valuable than the jam. - Joseph’s “just my thoughts”
