I work hard because I love my work.

I am surprised that in various countries, whether it's the U.K. or the U.S., you see isolationist tendencies that would tend to work against the co-operation, whether it's climate change, immigration, innovation, helping the very poorest. Those are things where you want to think across country boundaries and see a win-win-type solution.

Energy is actually harder; it takes more time to get a product, but if you do it's a very, very big market and the constraints of doing that in a clean way are more obvious all the time.

You have the refugee crisis triggered by Syria. That's got a lot of costs associated with it. Domestically, budgets are incredibly tight because the economy's not generating the growth that makes for easy trade-offs.

Software is definitely engineering. It's different in that we take on novel tasks every time. It's not like building a certain bridge that is virtually identical to some previous bridge or some previous building.

When I walk into a grocery store and look at all the products you can choose, I say, "My God!" No king ever had anything like I have in my grocery store today.

I find golf very relaxing. It's a way to get away from work and get outside. It's a lot of fun, and once you get going it's almost kind of addictive.
