The greatest business icons-it's not that they were worth hundreds of millions, or billions or trillions of dollars, it's that they moved society forward.

There are moments in business and in life when you have to say, "Failure is not an option."

Once you realize that there are no geniuses out there, you can think, "I can do that". One reason I've succeeded is that I have that naïve sense of entitlement.

The only thing I hated about the agency business was a lot of business travel. It was the only part of my job that I did not like. I found it very tedious and wearing.

The failure-dichotomy principle: failure is good. Failure is not an option. Balance those in your brain.

If you can't embrace both failure or the possibility of failure, or the tremendous fear of failure, you can't be wildly successful. It's just an axiomatic truth.

Every great business leader I've ever met, in addition to being very smart, very driven, they have this, 'Why not me? Screw it, I deserve it, let's go.' And if you don't have that, you can't achieve greatness.
