Duty: Memoirs of a Secretary at War by Robert M. Gates:
I didn’t socialize in Washington. Every day I had a fight of one kind or another—usually several—and every evening I could not wait to get home, get my office homework out of the way, write condolence letters to the families of the fallen, pour a stiff drink, wolf down a frozen dinner or carry-out (when Becky was in the Northwest), read something totally unrelated to my work life, and turn out the light.
I got up at five every morning to run two miles around the Mall in Washington, past the World War II, Korean, and Vietnam memorials, and in front of the Lincoln Memorial. And every morning before dawn, I would ritually look up at that stunning white statue of Lincoln, say good morning, and sadly ask him, How did you do it?
