I couldn't understand why my productivity went down when I had deliberately made more time available to write. Then I realized it was because I wasn't flying as much.

I'm pretty confident the why works now. When it first began, somebody said to me: "Will this work in big business?" I said, "I don't know. Let's try." Somebody said will this work in entrepreneurs, relationships or government and military. I said, "I don't know. Let's try." I kept applying the scientific method. I had a theory. I kept applying that theory, looking for opportunities to fail and it kept working.

I have been inspired by Martin Luther King and how he inspired a movement. I have learned that a cause must be organic; if it is to have an impact it must belong to those who join the movement and not those who lead it.

I'm simply following the journey.

The responsibility of the company is to help the people, grow as people. If we can do that, then the company will grow as a company.

A leader, first and foremost, is human. Only when we have the strength to show our vulnerability can we truly lead.

My challenge is to make sure the things I say and the things I do remain consistent for as often and as long as possible. My why is to inspire people to do the things that inspire them so that together we can change our world. That's why I wake up every single day. I'm agnostic to the form it takes: I teach, I write, I speak, I advise.
