I think the most important thing to do is to be willing to listen, willing to care, and willing to admit mistakes and change your ways for the better!

We have so far to go to realize our human potential for compassion, altruism, and love.

I had a wonderful teacher about animal behavior - my dog Rusty. He taught me that animals have personalities, minds, and feelings.

If you consciously say 'I won't do it!' to yourself, then you have a good chance that you won't.

It is these undeniable qualities of human love and compassion and self-sacrifice that give me hope for the future. We are, indeed, often cruel and evil. Nobody can deny this. We gang up on each one another, we torture each other, with words as well as deeds, we fight, we kill. But we are also capable of the most noble, generous, and heroic behavior.

The chimpanzees taught me a lot about nonverbal communication. The big difference between them and us is that they don't have spoken language. Everything else is almost the same: Kissing, embracing, swaggering, shaking the fist.

A chimp would never plan to pull another's nails out.
