The United States is at a critical juncture in time. Our government is riddled with historic debt and the limited resources of philanthropic and non-profit efforts cannot meet the scale of social challenges we face with necessary force.

There is a huge need and a huge opportunity to get everyone in the world connected to give everyone a voice and to help transform society for the future. The scale of the technology and infrastructure that must be built is unprecedented and we believe this is the most important problem we can focus on.

People should have freedom in their pilgrimages and tours. They should come and visit historical monuments and sites - let's say the sites around Iran - where they can easily engage in wide- scale contacts with others.

We think there's a good case for doing it now. We want to do it in an overall fiscally responsible way.

Small- and medium-sized businesses need access to a diverse range of finance options including non-bank lending. These new forms of finance are still small in scale today but they should over time bring additional choice and greater competition to the lending market.

The vast majority of large scale change efforts fail. Which means that the probability that you have actually experienced a failure and your people know that and are pessimistic therefore about trying something again is very high.

But in the back of my mind I've always looked to the biggest-scale Hollywood movies. Because to me the most satisfying experience is of watching a movie if it's done really well. And so that aspiration is always it for me if I have the opportunity to do it.

I never had any big dreams about doing something on a huge scale.

I tried the Atkins diet in the Seventies when pregnant with my son as I didn't want to pile on the pounds. Now so long as I'm healthy I don't care what my scales say.
