The time for change is now.

A sustainable world means working together to create prosperity for all.

The best change that comes to the world is when all parties are seeing each other as equal, and all parties have the opportunity to be transformed. That really goes back to the idea of dignity.

We need leaders, we ourselves need to lead from a place that has the audacity to believe that we ourselves can extend the fundamental assumption that all men are created equal to every, man woman and child on this planet. And we need the humility to recognize that we cannot do it alone.

Why do some people stop growing at age 30, just going from work to the couch and television, when others stay vibrant, curious, almost childlike into their nineties?

On the one hand, I loved being a banker. I loved how numbers could tell a story and how you can invest in ideas and see them translate into products and services and create jobs. What I didn't like, particularly where I was working in Brazil during the debt crisis of the early '80s, was how the poor were excluded from the banking system. I made the decision to try and experiment with whether we could use the tools of banking to extend the benefits of the economy to the poor.

The time for us to begin innovating and looking for new solutions is now.
