The Arab awakening was like watching elephants fly: something you didn't expect, something you haven't seen before, "Wow, elephants fly."

Obviously China is clearly taking the lead in some areas, but when it comes to the most advanced innovation, it's still America.

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. And this is in a world where we know that synthetic fertilizers and pesticides are toxic, and water is more and more scarce. Golf could do a lot more.

I've always believed the world would be a better place if more people everywhere have a chance to shape their own future and realize their full potential. I think that is what life is about.

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

I think the Arab awakening has changed everything and I think a lot will depend on what people there ask of us, may be nothing, it may be a lot. I think that really depends how they find their voice and what they see as their real interest, and hopefully that would be for more schools and not more tanks.

Something really big happened in the world's wiring in the last decade, but it was obscured by the financial crisis and post-9/11. We went from a connected world to a hyperconnected world. I'm always struck that Facebook, Twitter, 4G, iPhones, iPads, high-speech broadband, ubiquitous wireless and Web-enabled cellphones, the cloud, Big Data, cellphone apps and Skype did not exist or were in their infancy a decade ago.
