How are people like Angelina Jolie and Oprah inspiring others to help the world?

Angelina for her humanitarian efforts and the advocacy of adoption.Oprah for her many works not only on tv but to education and the improvement of education especially in Africa are some to name a few.These two women are the inspiration as well as role model.They represent the best a human has to offer the world and that is to help those in need.

They inspire by doing instead of telling others what to do or what needs to be done. I am not a regular watcher of Oprah so I don't know ahead of time when she is planning some activity. When I hear of what she does, as the girls' school in Africa, I am so amazed and wish I could do something good, too.

Jolie and Oprah are wonderful persons. They using something to be done not only spoken like politicians does.
Also second wife of Paul McCartney has foundation for helping people.
