 There's a bias in your brain called the liking bias. So to succeed, you have to be likable. And aggression is very dangerous because there's this game theory thing where the scientists in the 60s created game theory which said, how should you react to another person? And they ran a couple hundred million computer simulations and the answer is always start out nice unless you're in jail. If you're in a hostile situation like a prison where everybody's a known, aggressive person, then you start out mean. But in the real world of business, people are sensitive for different reasons. So I can't tell you how many times when people have observed me doing business network and they're like, everybody's nice. And I'm like, yes, yes. So my advice to you, if you feel like people are mean or something, hang out with a better quality people. High quality people are not mean. I promise you this.
