Poor leaders push us towards the goal. Great leaders guide us through the journey.

When I was in college, my school newspaper accepted an ad from a Holocaust revisionist organization. This would have been offensive on most college campuses across the country, but I went to a school with a very large Jewish population, so the ad, as you might expect, stirred absolute outrage.

I'm very prescriptive about who I work with. I'm very clear about what I believe. If they believe what I believe I will work with them. If they say things like, "Convince me we should do this." I walk away.

Great leaders must have two things: a vision of the world that does not yet exist and the ability to communicate that vision clearly.

Simple ideas are easier to understand. Ideas that are easier to understand are repeated. Ideas that are repeated change the world.

I never imagined I'd write a book.

People have accused me of only working with good companies. No I don't. I work with some very dysfunctional companies or unbelievably dysfunctional organizations. The people that bring me in know what they're doing won't work for the future. They know they want to change and they want to change for the right reasons. They believe what I believe and that's why they called me.
