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.

I don't think we've ever lived in such a dangerous time, on a range of different levels. We also live in an extremely exciting time with a multitude of opportunities for each and every one of us to engage our individual voices, to engage more effectively collectively, to tackle some of these issues that would have seemed beyond our reach just a few years ago.

You can see that in people around the world who struggle to survive with little or nothing. Whether they've been inspired by faith or by loving relationships, or whether it's just something innate that gives them that ability to shine and inspire others.

The idea of public service was instilled in me by watching my father, who shared that he was far more fulfilled in his public service than by his former lucrative corporate jobs.

We came together [with King Hussein of Jordan] because of a shared sense of idealism, of the value of service to a community far greater than ourselves, and the conviction that each and everyone of us can meaningfully contribute to solving even the most seemingly intractable problems.

The sheer folly of trying to defend a nation by destroying all life on the planet must be apparent to anyone capable of rational thought. Nuclear capability must be reduced to zero, globally, permanently. There is no other option.

All depend upon the engagement of as many people as possible on all levels, from civil society to national leaders, to advocate for the kind of national and international commitments, legislation, and public/ private partnerships that can make the difference.
