Land on Mars, a round-trip ticket – half a million dollars. It can be done.

The first stories I wrote when I was 12 were about Mars and landing on Mars.

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.

Space ails us moderns: we are sick with space.

The killer app that got the world ready for appliances was the light bulb. So the light bulb is what wired the world. And they weren’t thinking about appliances when they wired the world. They were really thinking about – they weren’t putting electricity into the home. They were putting lighting into the home.

I walk on untrodden ground. There is scarcely any part of my conduct which may not hereafter be drawn into precedent.

We’ve gotta become the Martians. I’m a Martian – I tell you to become Martians. And we’ve gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

The PC has improved the world in just about every area you can think of. Amazing developments in communications, collaboration and efficiencies. New kinds of entertainment and social media. Access to information and the ability to give a voice people who would never have been heard.

I don’t know where I’m going from here, but I promise it won’t be boring.

Ebooks had to happen.

It’s not a faith in technology. It’s faith in people.

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.

You can always think of something like the Xbox 360 as a super set-top box that can do everything the set-top box does, but then have the graphics to do the games as well.

Aviation offered such fun as crossing the continent in planes large and small, trying the whirling rotors of an autogiro, making record flights. With these activities came opportunity to know women everywhere who shared my conviction that there is so much women can do in the modern world and should be permitted to do irrespective of their sex.

Education must provide the opportunities for self-fulfillment; it can at best provide a rich and challenging environment for the individual to explore, in his own way.

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

Love is an adventure and a conquest. It survives and develops, like the universe itself, only by perpetual discovery.

When we understand string theory, we will know how the universe began. It won’t have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.

We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.

If you do not expect the unexpected you will not find it, for it is not to be reached by search or trail.

I do think there is a lot of potential if you have a compelling product and people are willing to pay a premium for that. I think that is what Apple has shown. You can buy a much cheaper cell phone or laptop, but Apple’s product is so much better than the alternative, and people are willing to pay that premium.

I have already demonstrated, by crucial tests, the practicability of signaling by my system from one to any other point of the globe, no matter how remote, and I shall soon convert the disbelievers.

For novelists or musicians, if they really want to create something, they need to go downstairs and find a passage to get into the second basement. What I want to do is go down there, but still stay sane.

If humanity doesn’t land on Mars in my lifetime, I would be very disappointed.

It’s not a real adventure when you have to pay for it.

The great quest of life has always been to discover truth.

I think – I don’t know, maybe it’s nostalgia. But the choice, losing the choice to be able to use film is going to be – it’s gone. It’s going to be gone.

What is Apple, after all? Apple is about people who think ‚outside the box,‘ people who want to use computers to help them change the world, to help them create things that make a difference, and not just to get a job done.

Ronald Reagan used to alarm his Soviet counterparts by saying that surely they’d both unite against an invasion from Mars.

The universe is wider than our views of it.

At Facebook, we build tools to help people connect with the people they want and share what they want, and by doing this we are extending people’s capacity to build and maintain relationships.

What we want to do is make a leapfrog product that is way smarter than any mobile device has ever been, and super-easy to use. This is what iPhone is. OK? So, we’re going to reinvent the phone.

What we want to be is something completely new. There is no physical analog for what Amazon.com is becoming.

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.

Once you have a computer that can do a few things – strictly speaking, one that has a certain ‚sufficient set‘ of basic procedures – it can do basically anything any other computer can do. This, loosely, is the basis of the great principle of ‚Universality‘.

The whole object of travel is not to set foot on foreign land; it is at last to set foot on one’s own country as a foreign land.

Cameras aren’t guns. They can’t really hurt you.

We will explore the mysteries of science and harness the power of technology and innovation. We will realise the opportunities of the digital world. Our youth will learn more from – and with – each other.

You can’t be in love with a Google search.

It is better to travel well than to arrive.

The desktop computer industry is dead. Innovation has virtually ceased. Microsoft dominates with very little innovation. That’s over. Apple lost. The desktop market has entered the dark ages, and it’s going to be in the dark ages for the next 10 years, or certainly for the rest of this decade.

Everyone seems to think that digital technology devoids the medium of content, but that is not true at all. If anything, it broadens the content.

Music itself is going to become like running water or electricity. So it’s like, just take advantage of these last few years because none of this is ever going to happen again. You’d better be prepared for doing a lot of touring because that’s really the only unique situation that’s going to be left.

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.

Poets say science takes away from the beauty of the stars – mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?

There’s nowhere else like London. Nothing at all, anywhere.

New discoveries in science will continue to create a thousand new frontiers for those who still would adventure.

Well, Apple invented the PC as we know it, and then it invented the graphical user interface as we know it eight years later (with the introduction of the Mac). But then, the company had a decade in which it took a nap.

Of all the inventions of humans, the computer is going to rank near or at the top as history unfolds and we look back. It is the most awesome tool that we have ever invented. I feel incredibly lucky to be at exactly the right place in Silicon Valley, at exactly the right time, historically, where this invention has taken form.

To the lover of wilderness, Alaska is one of the most wonderful countries in the world.

From the point of view of basic physics, the most interesting phenomena are, of course, in the new places, the places where the rules do not work – not the places where they do work! That is the way in which we discover new rules.

What do I care about Jupiter? Justice is a human issue, and I do not need a god to teach it to me.

Sometimes the greatest meals on vacations are the ones you find when Plan A falls through.

Never lose a holy curiosity.

Despite all I have seen and experienced, I still get the same simple thrill out of glimpsing a tiny patch of snow in a high mountain gully and feel the same urge to climb towards it.

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.

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

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.

Eventually we’ll be able to sequence the human genome and replicate how nature did intelligence in a carbon-based system.

Everybody around me had a Snapchat, and I said I would never get on it. I’m still on Instagram, you know? They convinced me to get Snapchat.

It took us three years to build the NeXT computer. If we’d given customers what they said they wanted, we’d have built a computer they’d have been happy with a year after we spoke to them – not something they’d want now.
