We're more than just our job titles or our list of professional accomplishments.

There may be no single thing that can teach us more about life than death.

The crisis in America that we barely notice anymore is that we've become two nations - divided by poverty, opportunity, and race. It's like a neighbor's car alarm that we don't hear anymore because it rings so often.

The first step toward changing the world is to change our vision of the world and of our place in it.

The next generation will remake the world in a way that allows us to live in a more sustainable way, both personally and globally.
