There are 20,000 million books I could have to read, but I can pick the ones and know that I'm learning something that I didn't know before. That's the glory of writing. It's not even so much the writing, it's what you learn - especially history - because so much of it is research.

When I look at Franklin Roosevelt's leadership, I think the most important quality he had during the Depression and the war was this absolute confidence in himself, in his country, really in the American people. He was able to exude that confidence and almost project it.

(from John Hay's diary) “The President never appeared to better advantage in the world,” Hay proudly noted in his diary. “Though He knows how immense is the danger to himself from the unreasoning anger of that committee, he never cringed to them for an instant.

Washington was a typical American. Napoleon was a typical Frenchman, but Lincoln was a humanitarian as broad as the world. He was bigger than his country - bigger than all the Presidents together. We are still too near to his greatness,' (Leo) Tolstoy (in 1908) concluded, 'but after a few centuries more our posterity will find him considerably bigger than we do. His genius is still too strong and powerful for the common understanding, just as the sun is too hot when its light beams directly on us.' (748)
