You have to really care about what you say. And if you don't, it will never come out quite right, unless you go into acting, in which case you have to act fast before you realize it is something which you do not believe in.

You can't do everything. You can't do health and forestry and agriculture. You've got to focus and do one or the other.

You better not mess with chimps. They are much stronger than humans.

Every stage of my life set the scene for the next, and at each point all I had to do was say "yes" and not think too much about the consequences.

We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts.

I think the best evenings are when we have messages, things that make us think, but we can also laugh and enjoy each other's company.

I just have this absolute belief that humans are moving away from cruelty and destruction towards a time when we can truly live in harmony with nature. When we understand that there is a spiritual power around us from which we can draw strength. That is where I believe human destiny ultimately is taking us. I just hope we have time.
