I've always managed by walking around. Any CEO or leader who spends the majority of his time in his office is not doing his job.

You know you're doing what you love when Sunday nights feel the same as Friday nights.

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.

To me, it’s always what’s next and I think that’s what drives most very successful people. It’s never about the money. I mean that’s a way of keeping score. It’s about achievement and it’s about winning a game and it’s about upping the ante.

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.

Changes in my personal life are nerve-racking for me.

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.
