It's a privilege to help usher in Nelson Mandela's Conversations with Myself, an international publishing event. We've selected President Barack Obama's foreword to the book as our monthly exclusive for Work in Progress readers. A preview is excerpted below. -Ryan Chapman "Like many people around the world, I came to know of Nelson Mandela from a distance, when he was imprisoned on Robben Island. To so many of us, he was more than just a man – he was a symbol of the struggle for justice, equality, and dignity in South Africa and around the globe. His sacrifice was so great that it called upon people everywhere to do what they could on behalf of human progress.
