A good heart
Dikembe Mutombo grew up in Africa among great poverty and disease. He came to Georgetown University on a scholarship(奖学金) to study medicine — but Coach(教练) John Thompson got a look at Dikembe and had a different idea. Dikembe became a star in the NBA, and a citizen of the United States. But he never forgot the land of his birth, or the duty to share his fortune with others. He built a new hospital in his old hometown in the Congo. A friend has said of this good-hearted man: “Mutombo believes that God has given him this chance to do great things.”
Success and kindness
After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children’s videos(录像) in her own house. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. And she is using her success to help others — producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new program: “I believe it’s the most important thing that I have ever done. I believe that children have the right to live in a world that is safe.”
Bravery and courage
