I don't think there is anything about putting your country first that requires you to turn your back on the rest of the world. If anything, the opposite is true.

The head of the Bank of England, Mervyn King, privately criticised David Cameron and George Osborne before the election for their lack of experience, the lack of depth in their inner circle and their tendency to think about issues only in terms of their electoral impact.

You must tell yourself the truth about money if you're going to give it away well. If you can't live well with $999 million, there's something clearly wrong with you. Money gets inside us; it creates our perceptions and changes the way we operate. It changes the people among whom we are, and who we are. When we're not in touch with that reality, it can change us in heinous ways.

what turns a developing into a developed nation is not the amount of foreign aid it attracts, but how the money is spent.

We don't change the world through opinions, we change it with examples. So I've been putting myself out there, reaching out and connecting.

I never, ever, thought – even remotely – that I would make this festival my life. It was never seen as something that would run forever – and was something which was very much done 'by the seat of our pants' you know? It was a miracle if we got through, one year at a time….

As I progressed in my career, there were always moments where I asked myself whether I was good enough for that next challenge. I was often the youngest person in the room, and typically the only brown face in the room. I took the fact that I felt I wasn't good enough as a challenge.

In the 18th century, they're kind of taking stock of how, in just about 100 years, all this classical learning had been overturned. Looking back on everything that's happened, they construct this narrative of how human reason has progressed.

Despite these needs, the reality is that more than half of the estimated 2.7 billion working age adults globally are excluded from formal financial services. Poor families, as far as access to financial services is concerned, are doubly penalised. They need financial access more than we do, but they only have access to inferior informal services.

There's a vested interest – if the ideas you're teaching and have worked on are completely abandoned in favour of something else, then your legacy goes to zero. I think that's a big force.

Always remember in life there will always be someone that will be in more in need. We could only afford a dime that year, but we gave to help out others!

I often hear people say that everything that matters must be measured, and if it can't be measured, it doesn't matter. I believe the absolute reverse. Nothing that matters can be measured. I don't think there's anything on this earth worth lifting a finger for that you can measure.
