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”
The advice to concentrate on one thing instead of trying to excel at many is valid, as it’s also challenging to master a single skill. If you neglect the other essential background abilities necessary to enhance that one skill, you will be unable to overcome your limitations. For a top-level skill to thrive, the supporting average abilities for that skill must also develop concurrently. Concentration should not be an excuse to avoid or ignore what’s important. - Joseph’s “just my thoughts”
