What I spend is someone else’s income. Apple co-founder Steve Jobs discussed every morning at breakfast with his family about buying a set of Miele washing machines and dryers from Germany for two weeks. Why? Of course, it was to teach their children about economics and to illustrate a lesson about opportunity cost, a common trait among wealthy people. If you buy this washing machine, you cannot buy that one. That is the opportunity cost. It’s a form of relative value, based on the idea that choosing one option means sacrificing another, so the value of each can be compared within those limits. Wealth begins with training in understanding even trivial opportunity costs. To succeed in business, you need to learn how to measure opportunity cost first, rather than just how to make money. - 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”
