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!

From my perspective, I absolutely believe in a greater spiritual power, far greater than I am, from which I have derived strength in moments of sadness or fear. That's what I believe, and it was very, very strong in the forest.

You aren't going to save the world on your own. But you might inspire a generation of kids to save it for all of us. You would be amazed at what inspired children can do.

It's easy to become hopeless. So people must have hope: the human brain, the resilience of nature, the energy of young people and the sort of inspiration that you see from so many hundreds of people who tackle tasks that are impossible and never give up and succeed.

Just remember--if you are really and truly determined to work with animals, somehow, either now or later, you will find a way to do it. But you have to want it desperately, work hard, take advantage of an opportunity--and never give up.

Every individual matters and has a role to play in this life on Earth.

Even in chimps there is true altruistic behaviour; behaviour that doesn't fit into the sociobiological model that says you either help a close relative and thereby your own genes, or you help somebody else now in return for their help in the future. When a very high-ranking male chimpanzee rescues a little orphan, saving his life, that kind of explanation doesn't work.
