When you are younger, you want to do everything, and you go haywire.

It is not possible for civilization to flow backwards while there is youth in the world. Youth may be headstrong, but it will advance it allotted length.

In past generations, people would try to play younger than they really are. My trick is, I don’t try to play younger than I really am.

It’s the journey of self, I guess. You start with this kind of loner, outside guy, which a lot of people can relate to, and he goes out into the world.

By seeing London, I have seen as much of life as the world can show.

I need more sex, OK? Before I die I wanna taste everyone in the world.

Most nations, as well as people are impossible only in their youth; they become incorrigible as they grow older.

I never drink coffee at lunch. I find it keeps me awake for the afternoon.

Nay, be a Columbus to whole new continents and worlds within you, opening new channels, not of trade, but of thought.

If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans.

I love travelling full stop – so while I’ve had some harrowing instances, I never look at them negatively. Memories are made when you’re travelling – not when you’re chained to your desk.

I still make sure to go, at least once every year, to a country where things cannot be taken for granted, and where there is either too much law and order or too little.

There is no sadder sight than a young pessimist.

The more one does and sees and feels, the more one is able to do, and the more genuine may be one’s appreciation of fundamental things like home, and love, and understanding companionship.

They are ill discoverers that think there is no land, when they can see nothing but sea.

Life’s a bit like mountaineering – never look down.

One can never know for sure what a deserted area looks like.

Perhaps one day I will go into space.

I set up situations that involve abandoning control and finding out what happens.

It is the youth who must inherit the tribulation, the sorrow… that are the aftermath of war.

Never lose a holy curiosity.

When a man is tired of London, he is tired of life; for there is in London all that life can afford.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun; as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.

Plunge boldly into the thick of life, and seize it where you will, it is always interesting.

I go to school the youth to learn the future.

Until 1914 I loved to travel; I often went to Italy and once spent a few months in India. Since then I have almost entirely abandoned travelling, and I have not been outside of Switzerland for over ten years.

For me, there are two types of people: the young and the experienced.

I am afraid that the schools will prove the very gates of hell, unless they diligently labor in explaining the Holy Scriptures and engraving them in the heart of the youth.

The revolution has always been in the hands of the young. The young always inherit the revolution.

The Youth of a Nation are the trustees of posterity.

The movement of search can only be from the known to the known, and all that the mind can do is to be aware that this movement will never uncover the unknown. Any movement on the part of the known is still within the field of the known.

Juvenile crime is not naturally born in the boy, but is largely due either to the spirit of adventure that is in him, to his own stupidity, or to his lack of discipline, according to the nature of the individual.

In my youth, I traveled much, and I observed in different countries, that the more public provisions were made for the poor, the less they provided for themselves, and of course became poorer. And, on the contrary, the less was done for them, the more they did for themselves, and became richer.

My son likes to go see mines and electric plants, or the Large Hadron Collider, and we’ve had a chance to see a lot of interesting stuff.

How could youths better learn to live than by at once trying the experiment of living?

Rebellion is what you make of it. When you’ve been on a tour bus for two months straight, and then you get in your car and drive wherever you want, that can feel rebellious.

Life is either a great adventure or nothing.

I think California has the best energy.

I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.

If I wished to do something, even if I couldn’t find anyone who wanted to make the effort with me, I would go out solo climbing. I did find solo climbing very challenging and a little frightening. You knew that you were completely on your own, and you had to overcome all the problems and possible dangers.

I’ve always been a bit of a gypsy.

I feel a distaste for hunting, first because of a kind of Buddhist respect for the unity and sacredness of all life, and also because the pursuit of a hare or chamois strikes me as a kind of ‚escape of energy,‘ that is, the expenditure of our effort in an illusory end, one devoid of profit.

Everybody is idealistic when you’re a kid.

Any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is is clearly a man to be reckoned with.

The mountains are calling and I must go.

Fires can’t be made with dead embers, nor can enthusiasm be stirred by spiritless men. Enthusiasm in our daily work lightens effort and turns even labor into pleasant tasks.

I’m more of an adventurous type than a relationship type.

I think all documentaries leave out areas of people’s lives. Which is good. There are areas that need not be explored.

You find no man, at all intellectual, who is willing to leave London. No, Sir, when a man is tired of London, he is tired of life; for there is in London all that life can afford.

It is unbecoming for young men to utter maxims.

The more that you read, the more things you will know. The more that you learn, the more places you’ll go.

However, because Britain is young and exciting, I did show my second line here once or twice.

A good traveler has no fixed plans, and is not intent on arriving.

Energy innovation is not a nationalistic game.

I want to work; then, as my kids get older, I want to have adventures. I want to visit all their countries: learn and live inside all their cultures.

Passion rebuilds the world for the youth. It makes all things alive and significant.

Going to Southeast Asia for the first time and tasting that spectrum of flavors – that certainly changed my whole palate, the kind of foods I crave. A lot of the dishes I used to love became boring to me.

I have often been downcast but never in despair; I regard our hiding as a dangerous adventure, romantic and interesting at the same time. In my diary, I treat all the privations as amusing.

I was scared many times on Everest, but this is all part of the challenge. When I fell down a crevasse, it was pretty scary.

Travel, in the younger sort, is a part of education; in the elder, a part of experience.

Curiosity is lying in wait for every secret.
