“I look around me, and I have so many friends who started companies who are worth $50 million and more, and they are depressed. They think they've made it, and they take six months off and they realize they're more depressed than ever. Because this wasn't really what ultimately it turned out life was all about. I look around me, and I see unhappy billionaires, and I see them coming back again and again to start another company. And what really attracts them is connecting with other people. It is the team. It's creating something. It's having a mission. That's what turns people on. That's what life is about.”
