I learned how to be a learner. When you get in a job, the tendency is to say, 'I've got to know it. I've got to give direction to others. I'm in this job because I'm better and smarter.' I always took a different view, that the key was to identify the people who really knew and learn from them.

Investing in early childhood nutrition is a surefire strategy. The returns are incredibly high.

When I became CEO of Xerox 10 years ago, the company's situation was dire. Debt was mounting, the stock sinking and bankers were calling. People urged me to declare bankruptcy, but I felt personally responsible for tens of thousands of employees.

There is an explosion of information happening, yet people demand quick access to relevant content that cuts through the clutter.

The day I was announced as CEO, I think the stock dropped another 20%.

I left Xerox for the non-profit sector because it was clear to me that only public/private partnerships can pull off a turnaround plan at the scale we need to tackle global poverty.

If we could muster the same determination and sense of responsibility that saves a country like Japan - or a company like Xerox - then investing to save women and children who are dying in the developing world would be very good business.
