Excellence in health means devoting your life to ending poverty.

People crave laughter as if it were an essential amino acid.

One cannot separate the health of the individual from the health of the community, from the health of the world.

We need each other, deeper than anyone ever dares to admit even to themselves. I think it is a genetic imperative that we huddle together and hold on to each other. There is no question in my mind that there is nothing else in life, really, than friendship.

You've got to know what you want. This is central to acting on your intentions. When you know what you want, you realize that all there is left then is time management. You'll manage your time to achieve your goals because you clearly know what you're trying to achieve in your life.

My first reaction was that the adult world was fake and liars and basically worked for money and power. I didn't want to live in that world, so I spent a year, aged 17 to 18, trying to kill myself. I didn't want to live in a world of violence and injustice.

If you want to change the world, then be your own focus for a celebration of life. Really, fundamentally, at the very core of your being, be thankful you are alive, that you've got this opportunity, with these molecules, at this moment. Be thankful! Be a celebrant! Be thankful that you are alive and then look around to see who else is at the party!
