As warriors, as humanitarians, they've taught me that without courage, compassion falters, and that without compassion, courage has no direction.

I've learned that courage and compassion are two sides of the same coin, and that every warrior, every humanitarian, every citizen is built to live with both. In fact, to win a war, to create peace, to save a life, or just to live a good life requires of us - of every one of us - that we be both good and strong.

I was worried that all the corners of the earth had been explored, all the great battles fought. The famous people on TV were athletes and actresses and singers. What did they stand for? I wondered: Had the time for heroes passed?

The best definition I have ever heard of a vocation is that it's the place where your great joy meets the world's great need. We need all of you to find your vocation. To develop your joys, your passions, and to match them to the world's great needs.

Life is short. Life is uncertain. But we know that we have today. And we have each other. I believe that for each of us, there is a place on the frontlines.

I begin with humility, I act with humility, I end with humility. Humility leads to clarity. Humility leads to an open mind and a forgiving heart. With an open mind and a forgiving heart, I see every person as superior to me in some way; with every person as my teacher, I grow in wisdom. As I grow in wisdom, humility becomes ever more my guide. I begin with humility, I act with humility, I end with humility.

...it's not enough to fight for a better world; we also have to live lives worth fighting for.
