I thought these quotes about being "too transperant" were pretty interesting:

"People want to know you're human, but not much more"

Oswald Sanders wrote, "The crowd doesn't recognize a leader until he's gone; then they build a monument for him with the stones they threw at him in life."

During my leave of absence, I heard the story of a general who was severely wounded in battle. He told a captain to bring his coat. The captain was bewildered at the request. The general said, "The troops can see some blood, but they cannot see me hemorrhage." I had shown my troops too much blood.
