If we want to be governed by someone we wouldn't do a business deal with because their background is so shady, if we're willing to do that, then that's in conflict with who I think we are. And so I think it's necessary at those times to take a stand.

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.

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.
