Buffett has said several times that if his father was a shoe salesman, he would probably be a shoe salesman now. It's not that selling shoes is bad, it's also an honor to be able to earn money to support yourself and your family. Yes, this is not a story about how to sell shoes, but to tell this story to illustrate the influence of a father on his children. Buffett's father was a bond salesman, which led to Buffett being exposed to the securities market and various stocks since he was a child, which was the key starting point for him to become a billionaire.
