The biggest opportunity in 2013 is in Africa. It has seven out of the ten fastest-growing economies in the world. In Nigeria alone there are 100 million people with mobile phones. In total, 300 million Africans - five times the population of Britain - are in the middle class.

The problems that the world faces - from nuclear proliferation to climate change - can't be tackled by the West alone. They need a coalition of not just West and East, but they need a coalition of Christian and Jew and Muslim.

This is nourishing, redemptive we become less alone inside.

I would say, 'I'm alone, but I'm not lonely.' But I was just kidding myself.

He who does not fill his world with phantoms remains alone.
