I think one of the main challenges that the World Bank faces is creating an organizational structure that doesn't get in the way of its staff. We have fantastic staff. People told me as I was coming into the organization that the greatest asset of the World Bank Group is its staff, and I think there's no question that that's the case.

One of the most important things about leadership is that you have to have the kind of humility that will allow you to be coached.

Look at the problem of drug-resistant TB in the world. Look at HIV in the world. What's going to be required for everybody in the long run is the ability to do complex health interventions in poor settings.

No matter how good you think you are as a leader, my goodness, the people around you will have all kinds of ideas for how you can get better. So for me, the most fundamental thing about leadership is to have the humility to continue to get feedback and to try to get better - because your job is to try to help everybody else get better.

Well, everybody is trying to make this a money thing. If you send me to another team, let's see what I ask for. I won't ask for nothing. I'll play under the same terms. So it is not Gary wants more money. Gary has money. What else do I need?

I only ever did one hotel room because at the end of the tour, I had a little less money than the rest of the guys, and the tour manager said, 'You remember that hotel room you destroyed in Iowa? Well, we had to pay for it.' And I was like, 'Ooooh. That's how it works.'

If you are starving and young and in search of answers as to why your life is so difficult, fundamentalism can be alluring. We know this for a fact because former members of Boko Haram have admitted it: They offer impressionable young people money and the promise of food, while the group's mentors twist their minds with fanaticism.

You need money to have advocacy in America. People that don't have money don't have advocacy.
