Albert Einstein was without a doubt a genius, one of the smartest humans of all time. But no one would ask Albert Einstein for a business advice. Flip the side, and everyone thinks that a successful businessman is a genius. The hypnosis of MONEY! What does it mean to be smart? Who is smarter: Einstein or Bezos? Newton or Zuckerberg, Musk, Gates? If you answer honestly, the next step is to accept that one does not have to be a genius in order to create and run a successful business. If you played the game of chess, you would know that the winner is the one who makes less mistakes. Same in business. Everyone starts something, but those who make less mistakes get eventually noticed. In the case of Mr. Bezos (and many other well-known white businessmen): good family, good education, Wall-Street experience, and - of course - boldness, taking a risk (for starters, just to start a start-up), and being persuasive (#1 and 2 and 3 professional quality of a businessman). Multiply by a good luck. Subtract missteps (“Fire phone”). Add learning from mistakes (Alexa). And having good genetics - which provided with a good brain - the physiological basis of thinking and effective learning.
I disagree with the last statement, but I know that I am in the minority on this (but not alone! http://www.cognisity.how/2018/04/bincome.html).
