Oprah Talks to Nelson Mandela
Nelson Mandela: All I can say is that I was less foolish than I was when I went in. I equipped myself by reading literature, especially classic novels such as The Grapes of Wrath. When I closed that book, I was a different man. It enriched my powers of thinking and discipline, and my relationships. I left prison more informed than when I went in. And the more informed you are, the less arrogant and aggressive you are.
