A Sinner Not A Saint: The Mandela Letters and Papers

Mandela's musings about himself and his relationships appear in a book pieced together from letters and papers he wrote before, during, and after his imprisonment. In one of these papers, he wrote:
"One issue that deeply worried me in prison was the false image I unwittingly projected to the outside world; of being regarded as a saint. I never was one, even on the basis of the earthly definition of a saint as a sinner who keeps trying." See this "60 Minutes" report on the book here.
