King Hussein never lost his faith, no matter how difficult and unbearable and cruel the circumstances could be. I always remember that. It helps me get through everything. It's a way of trying to keep that positive spirit alive for as many people as we can touch. I think that's good for the world.

I have witnessed firsthand the anguish of this humanitarian tragedy - in Palestine, Iraq, Syria, Pakistan, and other conflict and post-conflict zones. The destruction of lives and hopes, the emotional trauma, and the economic, social, and political marginalization of the displaced, the human insecurity, with real and potentially devastating consequences over generations, in ever-widening arenas of conflict. We can and must ensure the human rights of the displaced. That begins by making their voices heard.

I think there are always going to be fanatics and charismatic extremists who are going to be able to draw a following.

What keeps me awake at night is just, Am I making the best use of the time that remains for me, to both be as good an example as I can in my own daily life, and as compelling as possible a voice for the ways in which we can all work together to tackle these issues.

A more just world is possible. In most of the global issues, and also in so many of the development issues I'm involved in in our region, the young people that I am working with are seizing the tools at their disposal and trying to use them well, for issues far larger than their immediate personal benefit and concerns. That's what gives me hope.

Everyone I knew, including my new friends in Jordan, expressed horror at the realities of the Holocaust. But they resented, as I was growing to, how Arabs were cast as the aggressors in the dispute between Israel and the Arab countries, when it was their land that had been seized to resolve a European political problem.

Martin Luther King, Jr.'s peaceful, determined struggle for social justice, and Sargent Shriver, who launched the Peace Corps, were early heroes. A career of public service was the ultimate aspiration.
