The goal, then, isn't to draw some positioning charts and announce that you have differentiated your product. No, the opportunity is to actually create something that people choose to talk about, regardless of what the competition is doing.

Some people read business books looking for confirmation. I read them in search of disquiet. Confirmation is cheap, easy and ineffective. Restlessness and the scientific method, on the other hand, create a culture of testing and inquiry that can't help but push you forward.

Two elements of successful leadership: a willingness to be wrong and an eagerness to admit it.

We know what you want to accomplish... The real question is, 'what are you willing to push through the dip for?' What are you willing to stand up for, bleed for, commit to and generally be unreasonable about? Because that's what's going to actually get done.

If you could do tomorrow over again, would you?

I think if you're remarkable, amazing or just plain spectacular, you probably shouldn't have a resume at all.

Don’t do it because it’s your job, do it because you can.
