If I say any word, like, "Sit next to me." There is a chemistry inside of my brain and your brain that is figuring out what that means and turning that request into action. The brain is designed in a way to enable us to translate these strange interaction codes that people have with each other into something that can manifest a whole company's success. That's so extraordinary and that's what's going on. Everybody in the world needs to know that, in the whole planet. I just talked to somebody who studies cosmoses. She said, "Cosmoses need this."

Every human being needs to know to be a great parent, for a teacher to be a great teacher, and for a business partner to be a great business partner. We can't fall back on, "Oh, I only said it once and it didn't matter." That kind of phrase. That's a not-good thing for a leader to hold inside. If what that leader did is do that separation and this person now knew that they were not going to be on the popular team, doing it once and then not doing it again isn't enough to erase what just happened.

It turns out that human beings are hard-wired to have conversations impact them in such profound and significant ways that it can actually turn genes on and off. That's a core, fascinating challenge for all of us and insight.

I want to share that I had and still do, and a great relationship with Angela Ahrendts. She was the CEO of Burberry. One of the things that I saw her do at Burberry was that every person she screened for a job, they had to go through the trust test. Do they understand what trust even means. Do they consider it in their life. If people didn't pass that part of the test, they didn't get into Burberry, because she wanted a team. It was extraordinary to be with her, because she brought them to the height of their best behaviors, including trust, which is the most important thing here.

Human beings really think about relativity. That's part of what the brain does.

I've spent years studying words. Linguistics, language, the power of words, the power of phrases on human beings. All of that. It's part of my, almost obsessive, fascination. It turns out that there are some keys that we all need to know about how conversations impact us, because they do at a chemical level. There are certain things that if we learned this, it would totally change our interactions with others, and that's the following. There are certain words that have a feeling of, "I love you, I care for you, you're in my tribe."
