We must be ready to learn from one another, not claiming that we alone possess all truth and that somehow we have a corner on God.

We spend billions on banks when we know that a fraction of this money could save all the children in the world.

Resentment and anger are bad for your blood pressure and your digestion.

There are people who go to bed hungry, and that is unconscionable.
