If you don't visit the bad neighborhoods, the bad neighborhoods are going to visit you.

I basically did all the library research for this book on Google, and it not only saved me enormous amounts of time but actually gave me a much richer offering of research in a shorter time.

There is no substitute for face-to-face reporting and research.

I am hoping, though, that many of them have kids, who, when they have a moment to take a break from their iPods, Internet, or Google, will explain to their parents running the country just how the world is being flattened.

It created a global platform that allowed more people to plug and play, collaborate and compete, share knowledge and share work, than anything we have ever seen in the history of the world.

The Dell Theory of Conflict Prevention argues that no two countries that are both part of the same global supply chain will ever fight a war as long as they are each part of that supply chain.

McDonald's cannot flourish without McDonnell Douglas, the designer of the F-15.

Yes, the world is now flat for publishing as well.

Basically all the world's computer parts come from the same supply chain that runs from Korea, down through coastal China, over to Taiwan, and down to Malaysia.

Two things are going on at the same time with the flattening of the world: The relentless quest for efficiency is squeezing some of the fat out of life.

If you don't visit the bad neighborhoods, the bad neighborhoods are going to visit you.

We need to become energy independent or at least aspire to that.

I have a daughter who is a sophomore in college and another who is in the 11th grade of high school.

You win the presidency by connecting with the American people's gut insecurities and aspirations. You win with a concept.

We are led by lawyers who do not understand either technology or balance sheets.

Supply chains cannot tolerate even 24 hours of disruption. So if you lose your place in the supply chain because of wild behavior you could lose a lot. It would be like pouring cement down one of your oil wells.

The hidden hand of the market will never work without a hidden fist.

Sometimes, when my wife and I were going out to dinner, I would take my laptop with me and work in the car, so as to take advantage of the half hour going and coming.

No, most of our political elite has not realized that the world is flat.

I was in Bangalore, India, the Silicon Valley of India, when I realized that the world was flat.

The historical debate is over. The answer is free-market capitalism.

A golf course should aspire to generate as much energy as it consumes - golf should be leading the way toward energy net zero.

Al Qaeda is nothing more than a mutant supply chain. They're playing off the same platform as Wal-Mart and Dell. They're just not restrained by it. What is al Qaeda? It's an open source religious political movement that works off the global supply chain.

Al Qaeda is nothing more than a mutant supply chain. They're playing off the same platform as Wal-Mart and Dell. They're just not restrained by it. What is al Qaeda? It's an open source religious political movement that works off the global supply chain. That's what we're up against in Iraq. We're up against a suicide supply chain.

America still has the right stuff to thrive. We still have the most creative, diverse, innovative culture and open society - in a world where the ability to imagine and generate new ideas with speed and to implement them through global collaboration is the most important competitive advantage.

Being one of my sources is exhausting. It's not one interview and you're done. I keep going back until I feel like I understand everything.

Being really good at 'learning how to learn,' as President Bill Brody of Johns Hopkins put it, will be an enormous asset in an era of rapid change and innovation, when new jobs will be phased in and old ones phased out faster than ever.

By 'flat' I did not mean that the world is getting equal. I said that more people in more places can now compete, connect and collaborate with equal power and equal tools than ever before. That's why an Indian in Bangalore can take care of the office work of American doctors or read the X-rays of German hospitals.

Capitalism and political systems - like companies - must constantly evolve to stay vital.

Do you know what my favorite renewable fuel is? An ecosystem for innovation.

Every golf course should have its carbon rating on the scorecard, alongside its Course Rating, Slope, par and yardage.

Every sport needs its temple, its cathedral.

Golf has an ambivalent relationship with the environment. On one hand, it's a great preserver of open spaces. Golf doesn't pave the world - it helps to green the world. But the downside is, it uses a lot of fertilizer, pesticides and water.

Google attracts so much talent, it can afford to look beyond traditional metrics, like G.P.A. For most young people, though, going to college and doing well is still the best way to master the tools needed for many careers.

I attended public school with the same group of kids from K through 12.

I can see a day soon where you'll create your own college degree by taking the best online courses from the best professors from around the world - some computing from Stanford, some entrepreneurship from Wharton, some ethics from Brandeis, some literature from Edinburgh - paying only the nominal fee for the certificates of completion.

I firmly believe that the next great breakthrough in bioscience could come from a 15-year-old who downloads the human genome in Egypt.

I said that more people in more places can now compete, connect and collaborate with equal power and equal tools than ever before.

I think we have lost our groove as a country. One of the reasons was the attack on 9/11. We got knocked off our game. From a country that always exported hope we went into the business of exporting fear.

I'm a capitalist. I believe in capitalism. But capitalism only works if you have safety nets to deal with people who are naturally left behind and brutalized by it.

I'm from Minnesota. I'm optimistic. I mean, that's just who I am.

I've always enjoyed the communal side of Jewish life.

I've been a critic of the antiglobalization movement, and they've been a critic of me, but the one thing I respect about the movement is their authentic energy. These are not people who don't care about the world.

If the Republican Party continues to take the view that there must be no tax increases, we're stuck. Capitalism can't work without safety nets or fiscal prudence, and we need both in a sustainable balance.

If you don't have an ethic of conservation, you basically have a license to drive a Hummer through the Amazon.

If you followed this economic crisis and you do not think that the world is getting flatter, you are not paying attention. We saw the entire global economy at one time acting totally in sync. The real truth is the world is even flatter than I thought. Our mortgage crisis is killing Deutsche Bank. You still don't think the world is flat?

In Globalization 1.0, which began around 1492, the world went from size large to size medium. In Globalization 2.0, the era that introduced us to multinational companies, it went from size medium to size small. And then around 2000 came Globalization 3.0, in which the world went from being small to tiny.

Lord knows there's a lot of bad news in the world today to get you down, but there is one big thing happening that leaves me incredibly hopeful about the future, and that is the budding revolution in global online higher education.

Many authors hate to go on grinding book tours. But I've always found it a useful way to be a foreign correspondent in America and take the pulse of the country.
