 Almost 75% of self-made billionaires were in direct sales. Mark Cuban told me he was selling garbage bags door to door. Elon Musk, every night at 9 p.m., he would call all his sales managers in the entire United States and teach them how to sell. Bill Gates, at age 16, was on the phone selling computer stuff. He would lower his voice so they couldn't realize he was a teenager. Like, oh, this is William Gates. And he was doing phone sales. I call it the king of all skills. The king and queen direct sales and marketing. These billionaire guys are tough negotiators. That's sales, man. My millionaire friends, you can be like, you know, let's do a deal that's fair for both of us. Oh, not a billionaire. He's going to extract that last penny out of you. You better read a contract sent to you by a billionaire. I'm going to tell you that right now. You better not celebrate because they shook hands with you and said, we're going to do the deal that way. They will change the deal five seconds before it's over. I'm dealing with one of that right now.
