What billionaire Mark Cuban learned about businessMark Cuban says the boss who fired him from one of his first jobs didn't understand one huge business lesson. Cuban sold software before starting his first company. His boss cared more about the appearance of the store than actual business results. The boss asked Cuban to clean up and open the store, but Cuban has a big sale he wanted to close, so he asked someone else to cover for him while he made the deal.
When Cuban got back his boss didn't care about the deal and he fired him on the spot.
Cuban says, "He was more interested in the show and would never go on sales calls." "There's never been a company that succeeded without sales."
Cuban would know .. his net worth is $3.4 Billion
