Emails get reactions. Phone calls start conversations.

When someone asks for your time, and you put your phone away to talk to them... that's leadership.

Halloween is one of my favorite days of the year. I have a strict rule: I don't work on Halloween and I won't travel on Halloween. Not for any reason.

The true price of leadership is the willingness to place the needs of others above your own. Great leaders truly care about those they are privileged to lead and understand that the true cost of the leadership privilege comes at the expense of self-interest.

A star wants to see himself rise to the top. A leader wants to see those around him rise to the top.

Outside advice can only tell you how a decision looks. Only you can know how it feels. The best decisions look and feel right.

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.
