"Self-discipline manifests itself in countless ways. In a leader I see it as doing those things that should be done, even when they are unpleasant, inconvenient, or dangerous; and refraining from those that shouldn't, even when they are pleasant, easy, or safe. That discipline that causes a young lieutenant to check soldier's feet for blisters or trench foot, will also carry him across a bullet-swept street to support a squad under pressure."

“While I had enjoyed other jobs, I loved command. I had been in a command position for ten of the previous twenty-six years. But each new position was initially daunting. As I suspect many leaders feel, I was never sure if I could command at the next level until I actually assumed the job. I remembered how Douglas Southall Freeman, in Lee's Lieutenants, had described Lee's challenges in determining which brigade commanders could actually handle the responsibilities of a division or corps. The most aggressive brigade commanders often lacked the intangible qualities required for more senior leadership. Of course I often wondered about myself. As the demands of the positions differed, I found that I had changed as a leader. I learned to ask myself two questions: First, what must the organization I command do and be? And second, how can I best command to achieve that? Experience taught me that many factors would shape my "command style," and it would be some time before I had settled into it.”

“On May 19, 2009, I was taken to the White House to meet President Obama. We'd met once before when he'd visited the Pentagon during his first week in office, but as DJS I'd been in a collection of other civilian and military leaders, so it was unlikely he remembered the man who would soon command his military effort in Afghanistan. I'd been in the Oval Office before with President George W. Bush, but the atmosphere in the West Wing in the final and opening months of administrations differed perceptibly. Although it was four months into Obama's term, there was still a feeling of newness to the people, who moved with an air of excited purpose through the hallways. When the president was available, the door opened and Obama walked to the entrance to greet me into the room. The meeting was short, but cordial. The president offered no specific guidance but locked his eyes with mine and thanked me for accepting the responsibility.”

“When I entered West Point, some Americans still believed the Vietnam War might end honorably. By the time I graduated, South Vietnam did not exist. As cadets, we watched the war teeter and implode, and the historical sweep was not lost on us.”

“It became clear to me and to many others that to defeat a networked enemy we had to become a network ourselves.”

“As visible symbols, soldiers often receive praise or condemnation, and both reactions feel curiously undeserved.”

“When the ceremony ended Anne and I stayed on the field to greet friends, many of whom had traveled to share the ceremony with us. In one respect it was a difficult day at the end of a difficult month. But in the broader view of life, it was a magical evening at the end of an incredible journey we shared. We walked back over to the quarters we would move out of a few days later, and found friends in the yard and almost every room. At one point I saw Mike Hall, Charlie Flynn, Shawn Lowery, and Casey Welch standing in the fading summer light. I thought of my father, of my first day at West Point, and of our cold Christmas Eve flight over Afghanistan seven months before. The final words of my last speech in uniform, spoken just an hour before were repeated in my mind: "If I had it to do over again, I'd do some things in my career differently, but not many. I believed in people, and I still believe in them. I trusted and I still trust. I cared and I still care. I wouldn't have it any other way... To the young leaders of today and tomorrow, it's a great life. Thank you.”
