Should there be cameras everywhere in outdoor streets? My personal view is having cameras in inner cities is a very good thing. In the case of London, petty crime has gone down. They catch terrorists because of it. And if something really bad happens, most of the time you can figure out who did it.

There's a unique thing about the UK, where you give a very generous foreign aid budget to support globally, which is spent wisely. We partner with the government here to make sure that that money is spent well.

Your school may have done away with winners and losers, but life HAS NOT. In some schools they have abolished failing grades and they'll give you as MANY TIMES as you want to get the right answer. This doesn't bear the slightest resemblance to ANYTHING in real life.

We're changing the world with technology.

I think any statement about stock prices is always suspect unless it's made by Warren Buffett.

I was lucky to be in the right place at the right time. But many others were also in the same place. The difference was that I took action.

The next time someone tells you we can trim the budget by cutting aid, I hope you will ask whether it will come at the cost of more people dying.
