All sorts of torturers, dictators, fanatics, and demagogues struggling for power by way of a few loudly shouted slogans also enjoy their jobs, and they too perform their duties with inventive fervor. Well, yes, but they “know.” They know, and whatever they know is enough for them once and for all. They don’t want to find out about anything else, since that might diminish their arguments’ force. And any knowledge that doesn’t lead to new questions quickly dies out: it fails to maintain the temperature required for sustaining life.

one of the things that I learned from doing Design Matters from my guest Danny Shapiro, and I think I mentioned this in part one of my interview with Tim; confidence is overrated. Danny Shapiro has said that what is more important than confidence is courage.

I think authenticity is a crock, and I think authenticity is overrated and talked about far too much. The problem with authenticity is it’s selfish. Authenticity enables us to say whatever we want and if people don’t like it, well I was just being authentic. It is a ticket to self-absorbed inconsistency, and I don’t think anybody we serve wants that.

I've actually felt slightly uncomfortable at TED for the last two days, because there's a lot of vision going on, right? And I am not a visionary. I do not have a five-year plan. I'm an engineer. And I think it's really — I mean — I'm perfectly happy with all the people who are walking around and just staring at the clouds and looking at the stars and saying, “I want to go there.” But I'm looking at the ground, and I want to fix the pothole that's right in front of me before I fall in.

It is not the critic who counts; not the man who points out how the strong man stumbles or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, and comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who know neither victory nor defeat.
