This was a co-educational school, with many progressive features. The emphasis was on fostering curiosity rather than competitive excellence, and any kind of interest in examination performance and grades was severely discouraged. ("She is quite a serious thinker," I remember one of my teachers telling me about a fellow student, "even though her grades are very good.") Since I was, I have to confess, a reasonably good student, I had to do my best to efface that stigma.

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.

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 also knew that victimhood is not a virtue. That being discriminated against does not make you somehow morally better.

The most important single ingredient in the formula of success is knowing how to get along with people.

Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty…I have never in my life envied a human being who led an easy life. I have envied a great many people who led difficult lives and led them well.

Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the gray twilight that knows not victory nor defeat.

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.

I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life, the life of toil and effort, of labor and strife; to preach that highest form of success which comes, not to the man who desires mere easy peace, but to the man who does not shrink from danger, from hardship, or from bitter toil, and who out of these wins the splendid ultimate triumph.

Nothing in this world is worth having or worth doing unless it means effort, pain, difficulty. No kind of life is worth leading if it is always an easy life. I know that your life is hard; I know that your work is hard; and hardest of all for those of you who have the highest trained consciences, and who therefore always feel how much you ought to do. I know your work is hard, and that is why I congratulate you with all my heart. I have never in my life envied a human being who led an easy life; I have envied a great many people who led difficult lives and led them well.
