We sail within a vast sphere, ever drifting in uncertainty, driven from end to end.

The more I see the less I know for sure.

The pursuit of science leads only to the insoluble.

There is no subject so old that something new cannot be said about it.

Well, the odds must be against anybody being able to fly around the world in a balloon on the first attempt. All of us who are attempting to go around the world in balloons are effectively flying in experimental craft because these craft cannot be tested.

We are afraid to care too much, for fear that the other person does not care at all.

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

What’s coming will come and we’ll just have to meet it when it does.

There’s no point in making predictions. It’s not worth speculating because nothing is set in stone and things change all the time in football. Today there are opportunities that no one knows if they will come round again in the future.

I came to China to follow my star and to steep myself in the raw regions of the universe.

I don’t think you ever really know what all you’re doing, so you have to act on faith.

What is wanted is not the will to believe, but the will to find out, which is the exact opposite.

We’ve climbed the mighty mountain. I see the valley below, and it’s a valley of peace.

The word ‚romance,‘ according to the dictionary, means excitement, adventure, and something extremely real. Romance should last a lifetime.

Ever since the morning of May 29, 1953, when Tenzing Norgay and I became the first climbers to step onto the summit of Mount Everest, I’ve been called a great adventurer.

Curiosity is lying in wait for every secret.

It is only by risking our persons from one hour to another that we live at all. And often enough our faith beforehand in an uncertified result is the only thing that makes the result come true.

Early on, when I was quite young and going from job to job, I was foolish enough to sometimes speak to my fellow workers: ‚Hey, the boss can come in here at any moment and lay all of us off, just like that, don’t you realize that?‘ They would just look at me. I was posing something that they didn’t want to enter their minds.

Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts.

America is not nearly done. We’re only in the beginning. Who knows who we will be? Who knows… what color we will be? It is all something that, maybe, our descendants – if they survive that long – will see.

To confine our attention to terrestrial matters would be to limit the human spirit.

Once you get into this great stream of history, you can’t get out.

Any man can call time out, but no man can say how long the time out will be.

No one remembers who climbed Mount Everest the second time.

Marriage is an adventure, like going to war.

Over the last 15 months, we’ve traveled to every corner of the United States. I’ve now been in 57 states? I think one left to go.

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

I enjoyed climbing with other people, good friends, but I did quite a lot of solo climbing, too.

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

Yeah, I like to keep myself interested – I’ll kind of throw myself into some area that I don’t completely know or understand, that I’m not adept at, so I’m forced to swim in order to stay afloat. There’s a good feeling that comes from that.

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

We know what we are, but know not what we may be.

A queer fellow and a jolly fellow is the grasshopper. Up the mountains he comes on excursions, how high I don’t know, but at least as far and high as Yosemite tourists.

As soon as questions of will or decision or reason or choice of action arise, human science is at a loss.

I’ve been pleased to work with so many wonderful stars through the years. This has been an amazing journey. I hope it continues.

If you aren’t in the moment, you are either looking forward to uncertainty, or back to pain and regret.

This is the first age that’s ever paid much attention to the future, which is a little ironic since we may not have one.

I don’t have all the answers.

Anytime I feel lost, I pull out a map and stare. I stare until I have reminded myself that life is a giant adventure, so much to do, to see.

The clearest way into the Universe is through a forest wilderness.

Nobody climbs mountains for scientific reasons. Science is used to raise money for the expeditions, but you really climb for the hell of it.

There’s a certain amount of freedom involved in cycling: you’re self-propelled and decide exactly where to go. If you see something that catches your eye to the left, you can veer off there, which isn’t so easy in a car, and you can’t cover as much ground walking.

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

I’m not a parenting expert. In fact, I’m not sure that I even believe in the idea of ‚parenting experts.‘ I’m an engaged, imperfect parent and a passionate researcher. I’m an experienced mapmaker and a stumbling traveler. Like many of you, parenting is by far my boldest and most daring adventure.

Love can consign us to hell or to paradise, but it always takes us somewhere.

The uncertainty of parenting can bring up feelings in us that range from frustration to terror.

The Edge… there is no honest way to explain it because the only people who really know where it is are the ones who have gone over.

Science has explained nothing; the more we know the more fantastic the world becomes and the profounder the surrounding darkness.

Of course humans like to explore, and we should. There’s nothing wrong with that. But it’s more than that. It’s essential for your children and your children’s children.

He who would learn to fly one day must first learn to stand and walk and run and climb and dance; one cannot fly into flying.

Life is a constant oscillation between the sharp horns of dilemmas.

Life is like a wheel. Sooner or later, it always come around to where you started again.

Truth is a pathless land.

Generally speaking, a howling wilderness does not howl: it is the imagination of the traveler that does the howling.

Nothing in life is promised except death.

Not knowing when the dawn will come I open every door.

On life’s vast ocean diversely we sail. Reasons the card, but passion the gale.

Only by going alone in silence, without baggage, can one truly get into the heart of the wilderness. All other travel is mere dust and hotels and baggage and chatter.

I love to travel, but hate to arrive.

One of the things that we’re trying to do with Creative Labs and all our experiences is explore things that aren’t all tied to Facebook identity. Some things will be, but not everything will have to be, because there are some sets of experiences that are just better with other identities.

I cannot discover that anyone knows enough to say definitely what is and what is not possible.
