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, in… - Stanley A. McChrystal

All leaders are human. They get tired, angry, and jealous and carry the same range of emotions and frailties common to mankind. Most leaders periodically display them. The leaders I most admired were totally human but constantly strove to be the best humans they could be. Leaders make mistakes, and they are often costly. The first reflex is normally to deny the failure to themselves; the second is to hide it from others, because most leaders covet a reputation for infallibility. But it's a fool's dream and inherently dishonest. There are few secrets to leadership. It is mostly just hard work. More than anything else it requires self-discipline. Colorful, charismatic characters often fascinate people, even soldiers. But over time, effectiveness is what counts. Those who lead most successfully do so while looking out for their followers' welfare.

What I would ask every American to do is, again, stand in front of that mirror and say, what are we about? Am I really willing to throw away or ignore some of the things that people do that are pretty unacceptable, normally, just because they accomplish certain other things that we might like?

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.
