My mother always used to say, 'Well, if you had been born a little girl growing up in Egypt, you would go to church or go to worship Allah, but surely if those people are worshipping a God, it must be the same God' - that's what she always said. The same God with different names.

I miss the early days; I do. I was so lucky. I basically had it to myself, learning about these chimpanzees. Nobody knew anything about them. Discovering their different personalities, different life histories. I was lucky.

I didn't want to become a professor or get tenure or teach or anything. All I wanted to do was get a degree because Louis Leakey said I needed one, which was right, and once I succeeded I could get back to the field.

The chimpanzee study was - well, it's still going on, and I think it's taught us perhaps more than anything else to be a little humble; that we are, indeed, unique primates, we humans, but we're simply not as different from the rest of the animal kingdom as we used to think.

My dad would give me $10, which is a lot of money when you're 9, to sing at church, on tables at restaurants, at family functions, just about anywhere.

My first venture was to trade bicycle parts and hosiery yarn. The initial days proved to be difficult, and I earned very little from my business. But I kept at it. Each day, when I retired for the night, I told myself that money would come in the next day.

In some families, parents don't read or don't have the money to spend on books.

Money can buy you a fine dog, but only love can make him wag his tail.
