About once a year I like to introduce our web audience to extraordinary people who are making a difference in the world. Sometimes they are artists or visionaries, and sometimes just ordinary people who do extraordinary things. I am presently in South Africa, where the story of Thulani Ndebele came to my attention. Thulani is from Zimbabwe, and his story of heroism and courage in helping his village people deserves to be shared, as it acts as an inspiration to all of us and shows the power of the will, when backed with vision, to make a difference.
