What advice would you give your twenty-year-old self, and what should they ignore?

Come on now all you young men, all over the world. You are needed more than ever now to fill the gap of a generation shorn by the War. You have not an hour to lose. You must take your places in life's fighting line. Twenty to twenty-five! These are the years! Don't be content with things as they are. 'The earth is yours and the fulness thereof'. Enter upon your inheritance, accept your responsibilities. Raise the glorious flags again, advance them upon the new enemies, who constantly gather upon the front of the human army, and have only to be assaulted to be overthrown. Don't take No for an answer. Never submit to failure.

Courage is more exhilarating than fear and in the long run it is easier. We do not have to become heroes overnight. Just a step at time, meeting each thing that comes up, seeing it is not as dreadful as it appeared, discovering we have the strength to stare it down.

So I wish to you—I have no more time, so I have just one wish for you—the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom. May I also give you one last bit of advice: Never say that you'll give a talk unless you know clearly what you're going to talk about and more or less what you're going to say.

Always remember that it's much easier to apologize than to get permission. In this world of computers, the best thing to do is to do it.

When I recall my own path of life I cannot but speak of the violence, hatred and lies. A lesson drawn from such experiences, however, was that we can effectively oppose violence only if we ourselves do not resort to it.

History was not written by men who predicted failure, who gave up their dreams, who abandoned their principles, who allowed their laziness to put their intelligence to sleep. If certain men at times were alone in seeking victory, they always had at their side the watchful spirit of their peoples, the faith and destiny of many generations.

You never follow the crowd. You work things out for yourself. And therefore if you think differently from the crowd, you must put your own view and try to get people taking your line. But you never follow the crowd. You never do things just because other people are doing them.

They encouraged me, the way I do others now, that if you really have something that you like to do, that’s what you probably should do. Despite what everybody says, that you can’t make a living, or that’s not practical, or a thousand reasons why you may not do this or this or this. If that’s what your heart says you should do, chances are that you ought to listen.

When I went through school, I was in a hurry. I was an economics major as an undergraduate, and I was a finance major in graduate school. I was in a hurry to succeed when I got out in the business world. I’m sorry I didn’t take more courses in the humanities and in history and in the arts.

Study. Be honest. Don’t violate the laws and get in trouble. Get you a good spouse that will support you, because you never stop working and studying. The fact that you get the place just means you’ve started as far as the work and the pressure is concerned. That’s the only advice I’d know to give.

You have to be intelligent, and be able to cope with stress. It is a stressful life, both mentally and physically. Those are the qualities to succeed as a surgeon.

But whenever you do find something — maybe it’s not as passionate for you as dog mushing has been for me — but the fact that you have any interest, that is what you should go with.

I would advise them to aim high. To set their sights at a pretty tough target and don’t be too worried if you’re not successful at first. Just keep persisting and keep improving your standards, getting better and better and ultimately, you’ve got a pretty fair chance at achieving your desired goal. ... But, I do think that virtually everybody that’s born has the ability to be very competent at doing something. I think that, in itself, is worthy of aiming towards, just to be competent at doing anything you particularly wish to do.

The advice I would give any young person is, first of all, to rid themselves of prejudice against other people and to be concerned about what they can do to help others. And of course, to get a good education, and take advantage of the opportunities that they have. In fact, there are more opportunities today than when I was young.

The sky has turned brighter. There is a glorious rainbow that beckons those with the spirit of adventure. And there are rich findings at the end of that rainbow. To the young and the not too old, I say, look at the horizon, find that rainbow, go ride it. Not all will be rich; quite a few will find a vein of gold; but all who pursue that rainbow will have a joyous and exhilarating ride and some profit.

I go back to this idea that I only discovered when I was older. I wish I had known it when I was younger, because I think I missed a lot of observations in life. That is to develop your own philosophy. I always thought philosophy was one of the most useless subjects in the world.

The advice that I would give is try to find something that you like. Try to devote your energies to being very good at it. Try to achieve excellence. Don’t necessarily have as a goal success or getting prizes or whatever, but just doing very good work. And work hard. Keep working at it. Be patient. Realize that you don’t always see the benefits of what you’re doing, short-term. But in the end, the activities that I do, for example, scientific research, can be extremely rewarding. It’s really a very fascinating career.

Sensitivity. Be sensitive in every way possible about everything in life. Be sensitive. Insensitivity brings indifference and nothing is worse than indifference. Indifference makes that person dead before the person dies.

The most important piece of advice that I could give them is to take advantage of the tremendous reservoir of knowledge that’s out there today. Spend some time learning how the world has evolved. There are a lot of good lessons in history, and other peoples’ experiences in the past, that could be exactly the solution to the problem you’re looking for.

Having advanced well beyond what the French call "a certain age," I am often asked to convey to younger people helpful advice and counsel. So I will open these remarks with the best advice I ever received. The advice, which I have several times shared with others, was given to me by my mother-in-law on my wedding day. She had a prescription for a happy, enduring marriage: "It pays," she said, "it pays sometimes to be a little deaf."
