Manners make the world work. They're not only based on kindness but also efficiency. When people know what to do, the world is smoother. When no one knows what to do, it's chaos.

The best thing we can do to save the planet is set a good example for our kids at home.

Make people have a smile when they finish your e-mail.

Whatever they do, criminals and non-criminals act in particular ways. Some writers, for instance, use computers, others pen and paper. Some write in the morning, some at night. Each writer has a distinct style, with variations in grammar, sentence structure, and voice.

Because of the terrorist threat, the FBI and CIA have become as important as the military in preserving our freedom. Yet while thanking our military is standard practice in American life, no one thinks of thanking the FBI, the CIA, or the rest of the intelligence community for keeping us safe since 9/11.

While most Americans know about the Boston Tea Party, few are aware of the Liberty Tree and how important it was to fanning the flames of rebellion that led to the revolution in 1775 and the Declaration of Independence.

The 9/11 commission recommended the appointment of a national intelligence director with budgetary authority to better coordinate the work of the intelligence community and resolve differences.

When I left Apple, it had $2 billion of cash. It was the most profitable computer company in the world - not just personal computers - and Apple was the number one selling computer.

As a brand marketer, I'm a big believer in 'branding the customer experience,' not just selling the service.

The future belongs to those who see possibilities before they become obvious.

I have found that I always learn more from my mistakes than from my successes. If you aren't making some mistakes, you aren't taking enough chances.

If net neutrality goes away, it will fundamentally change everything about the Internet.

I just became one with my browser software.

Originally, I was in both software and in online computing. The first innovation really was sort of at that time that we're marrying the telephone and the computer so that people wouldn't have to drive to the computer center. We didn't have $1,000 computers.

One of the problems with computers, particularly for the older people, is they were befuddled by them, and the computers have gotten better. They have gotten easier to use. They have gotten less expensive. The software interfaces have made things a lot more accessible.

One of the biggest challenges we had in the first decade was not that many people had personal computers. There weren't that many people to sell to, and it was hard to identify them.

I do think that a general liberal arts education is very important, particularly in an uncertain changing world.

You have to get along with people, but you also have to recognize that the strength of a team is different people with different perspectives and different personalities.

And I'd say one of the great lessons I've learned over the past couple of decades, from a management perspective, is that really when you come down to it, it really is all about people and all about leadership.

My father still is a lawyer, and my mom was a teacher and then later a career counselor.

Why does everyone think the future is space helmets, silver foil, and talking like computers, like a bad episode of Star Trek?

As I get older, I just prefer to knit.

I think serial monogamy says it all.

Elon Musk is talking about silicon nanoparticles pulsing through our veins to make us sort of semi-cyborg computers. But why not take a noninvasive approach? I've been working and trying to think and invent a way to do this for a number of years and finally happened upon it and left Facebook to do it.

I've found that people who design computers don't know a lot about displays.

This is a man who was 23 years old when he theorized the idea of creating a programmable machine, and in that way, Turing foresaw computers and artificial intelligence. These were revolutionary ideas at that time.

I'm such a romantic at heart.

I think that what computers have done is just disastrous to the language.

I'm a teller of stories. I put bloody skins on my back and dance around the fire, and I say what the hunt was like. It's not erudite; it's not intellectual. I sail, run dogs, ride horses, play professional poker, and tell stories about the stuff I've been through. And I'm still a romantic; I still want Bambi to make it out of the fire.

Man-made computers are limited in their performance by finite processing speed and memory. So, too, the cosmic computer is limited in power by its age and the finite speed of light.

Is there anything science should not try to explain? Science is knowledge and knowledge is power - power to do good or evil. Sometimes ignorance is bliss.

Astronauts have been stuck in low-Earth orbit, boldly going nowhere. American attempts to kick-start a new phase of lunar exploration have stalled amid the realisation that NASA's budget is too small for the job.

Clearly, some creative thinking is badly needed if humans are to have a future beyond Earth. Returning to the Moon may be worthy and attainable, but it fails to capture the public's imagination. What does get people excited is the prospect of a mission to Mars.

When I write a song, I always start on acoustic guitar, because that's a good test of a song, when it's really open and bare. You can often mislead yourself if you start with computers and samples and programming because you can disguise a bad song.

Google is about information and computers and making things really fast. Facebook is about the sharing and connections. These missions give these companies direction and motivation.

I am cursed with computers; something always goes wrong.

I don't believe in cutting out people from the past. It doesn't give strength; it just gives loneliness.

Marriage is another trap. If you are someone who likes independence, it's another stamp against that. And you have to swear to fidelity.

Because I believe that humans are computers, I conjectured that computers, like people, can have left- and right-handed versions.

Our lives sometimes depend on computers performing as predicted.

The hardships that I encountered in the past will help me succeed in the future.

Because I am not formally trained in the medical sciences, I can bring in new ideas to AIDS research and the cross-fertilization of ideas from different fields could be a valuable contribution to finding the cure for AIDS.

The great advance of personal computers was not the computing power per se but the fact that it brought it right to your face, that you had control over it, that were confronted with it and could steer it.

All imaginable futures are not equally possible.

An organization's intelligence is distributed to the point of being ubiquitous.

We are infected by our own misunderstanding of how our own minds work.

Species go extinct because there are historical contraints built into a given body or a given design.

Organisms by their design are not made to adapt too far.

We didn't know the importance of home computers before the Internet. We had them mostly for fun, then the Internet came along and was enabled by all the PCs out there.
