All of the great leaders have had one characteristic in common: it was the willingness to confront unequivocally the major anxiety of their people in their time. This, and not much else, is the essence of leadership.
The high sentiments always win in the end, the leaders who offer blood, toil, tears, and sweat always get more out of their followers than those who offer safety and a good time. When it comes to the pinch, human beings are heroic.
The final test of a leader is that he leaves behind him in other men the conviction and the will to carry on. The genius of a good leader is to leave behind him a situation which common sense, without the grace of genius, can deal with successfully.
The person who renders loyal service in a humble capacity will be chosen for higher responsibilities, just as the biblical servant who multiplied the one pound given him by his master was made ruler over ten cities...
It is very comforting to believe that leaders who do terrible things are, in fact, mad. That way, all we have to do is make sure we don't put psychotics in high places and we've got the problem solved.
