Great leaders don't blame the tools they are given. Great leaders work to sharpen them.

I never imagined working with CEOs, congressmen or the military, yet I make regular visits to the Pentagon, stop by the Capitol now and then and sit down with leaders of all kinds of companies.

The quality of a leader cannot be judged by the answers he gives, but by the questions he asks.

Too many people write books as a calling card.

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.

The ones who show up to take, they show up and say, "Hi. My name is Steve. I'm an expert in this and I've studied this and I've worked with these clients." On every single power point presentation, it has their email, their Twitter handle and their Facebook account, so you can follow them. At the end, they tell you, "Please follow me." When you ask them a question, they say, "Well, I could tell you the answer, but you should really just read my book."

I put messages out there that start with why and they talk about what I believe. They go on to demonstrate and give examples. If it resonates with others, those with whom it resonates will share it with their friends and say, "This inspired me. You should watch it. You should read this."
