“One of the newest figures to emerge on the world stage in recent years is the social entrepreneur. This is usually someone who burns with desire to make a positive social impact on the world, but believes that the best way of doing it is, as the saying goes, not by giving poor people a fish and feeding them for a day, but by teaching them to fish, in hopes of feeding them for a lifetime. I have come to know several social entrepreneurs in recent years, and most combine a business school brain with a social worker's heart. The triple convergence and the flattening of the world have been a godsend for them. Those who get it and are adapting to it have begun launching some very innovative projects.”

“When widely followed public figures feel free to say anything, without any fact-checking, it becomes impossible for a democracy to think intelligently about big issues.”

“Pessimists are usually right and optimists are usually wrong but all the great changes have been accomplished by optimists.”

“America is the greatest engine of innovation that has ever existed, and it can't be duplicated anytime soon, because it is the product of a multitude of factors: extreme freedom of thought, an emphasis on independent thinking, a steady immigration of new minds, a risk-taking culture with no stigma attached to trying and failing, a noncorrupt bureaucracy, and financial markets and a venture capital system that are unrivaled at taking new ideas and turning them into global products.”

“No two countries that both had McDonald's had fought a war against each other since each got its McDonald's”

“In my world, you don’t get to call yourself “pro-life” and be against common-sense gun control — like banning public access to the kind of semiautomatic assault rifle, designed for warfare, that was used recently in a Colorado theater. You don’t get to call yourself “pro-life” and want to shut down the Environmental Protection Agency, which ensures clean air and clean water, prevents childhood asthma, preserves biodiversity and combats climate change that could disrupt every life on the planet. You don’t get to call yourself “pro-life” and oppose programs like Head Start that provide basic education, health and nutrition for the most disadvantaged children...The term “pro-life” should be a shorthand for respect for the sanctity of life. But I will not let that label apply to people for whom sanctity for life begins at conception and ends at birth. What about the rest of life? Respect for the sanctity of life, if you believe that it begins at conception, cannot end at birth.”

“Virulence is the sound of a self-selecting community talking to itself and positively reinforcing itself with no obligation to answer to anyone or look anyone in the eye.”

“No low-trust society will ever produce sustained innovation.”

“You have to trust that the dots will somehow connect in your future.”

“A Nobel Prize winner was asked how he became a scientist. He said that every day after school, his mother would ask him not what he learned but whether he asked a good question today. That, he said, was how he became a scientist.”

“Goods are traded, but services are consumed and produced in the same place. And you cannot export a haircut. But we are coming close to exporting a haircut, the appointment part. What kind of haircut do you want? Which barber do you want? All those things can and will be done by a call center far away.”
