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”
Expertise is not “to know only me,” but “to make understanding others to know with what only I know for.” It is not expertise if I cannot persuade others by overwhelming them with my things. The expertise that failed to convince and communicate is called “stubbornness”. “Collective intelligence” is the expertise that succeeds in persuasion and communication, and does not mean a stubbornness that enforces consensus. - Joseph’s “just my thoughts”
