We could change the world tomorrow if all the millions of people around the world acted the way they believe.

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!

I've always felt you don't have to be completely detached, emotionally uninvolved to make precise observations. There's nothing wrong with feeling great empathy for your subjects.

But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees.

A book came out recently written by scientists and environmentalists that made me so angry. It said the only thing we have to worry about is big industry. Each individual who tries to make his or her own environment better is useless. I find this criminal, because then you have a billion people all saying, It doesn't matter what I do because I'm just one person. But if you turn that around and a billion people say, What I do does make a difference, then it will make a difference.

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

I love to write - it is a great source of reflection, especially as I continue to meet many new inspiring people.
