It’s a common misconception that successful CEOs are always highly educated. It makes sense to think that executives must be highly experienced, but that experience doesn’t need to have started in college. In fact, there are a lot of hugely successful CEO millionaires who built their careers in blue-collar industries — and the lessons they’ve learned as leaders contain unique insights that one might not otherwise hear.
For instance, Bernie Marcus and Arthur Blank — the co-founders of Home Depot — emphasize how important it is not just to make sure a company’s mission is built on good values, but that those values are also held by all employees. “If the front line isn’t absolutely committed to the cause, we can’t win,” they write in their book, Built from Scratch: How a couple of Regular Guys Grew the Home Depot from Nothing to $30 Billion.
