Years of concentration solely on work and individual success meant that in his retirement [Lyndon Johnson] could find no solace in family, in recreation, in sports or in hobbies. It was almost as if the hole in his heart was so large that even the love of a family, without work, could not fill it.

Even though Lyndon Johnson's presidency was in many ways scarred forever by the war in Vietnam, and destroyed in a lot of ways, he - as a character - was even larger than his presidency.

When you are an historian, there's probably nothing that matters more than to be recognized by your colleagues in your own profession. I was lucky enough to win the Pulitzer Prize for History. I had to give a talk right after that to some young people. The most important thing to tell them, I think, is that you can't ever know that it's going to turn out that way.
