Never give up
Jane was not very interested in animals when she was a child. Then, one day, her father gave her a toy chimpanzee. From that day on, she became really interested in animals.
When she was a 16-year-old schoolgirl, Jane dreamt of a career studying wild animals in Africa.
Jane's mother said, "If you really want something, work hard and never give up. Then you'll find a way."
Jane's mother was right. When she was 26, Jane travelled from Britain to the mountains of East Africa. She studied chimpanzees. She watched the animals for a long time and they became her friends. Jane discovered that these animals greet one another with a kiss or a hug, and make and use tools—just like humans do.
Jane Goodall is now well known all over the world. She made her dreams come true because she never gave up!
