Sandy was a climate change warning. Obama must now take the stage and fulfil the promise of hope the world needs.

Many people theorize poverty, but so many elements of poverty, individually, for most people who theorize about poverty would be really difficult to even comprehend the individual things. Just take homelessness. If you are homeless, what does it mean not to have a post box where people can contact you; what does it mean not knowing where you're going to sleep at the end of the day; what does it mean not having a place where you can store what little you might possess. So dealing with homelessness in itself is a huge thing for most people who are commentators [on] or benefactors to poverty.

My final advice for young people is to not wait for leadership from adult politicians. Step forward today, because our current leaders are denying the dire reality we are facing. Leadership can come form anywhere.

Whenever anybody called Nelson Mandela a saint, he would say: "If by saint you mean a sinner who is trying to be better, then I'm a saint."

Nelson's Mandela own sense of himself was a very humble reading, [different] from how the world read him. And, quite often, you had the sense that he was not comfortable with all the accolades that would be.

[Nelson] Mandela was very keen not to be understood as an exceptional person.

I've come across a lot of people in my life who talk about poverty and talk about the poor, but you rarely have a sense that it matters to them to the point at which they will be willing to sacrifice something.
