The real power of effective leadership is maximizing other people’s potential which inevitably demands also ensuring that they get the credit. When our ego won’t let us build another person up, when everything has to build us up, then the effectiveness of the organization reverts to depending instead on how good we are in the technical aspects of what we do. And we have stopped leading and inspiring others to great heights.
There is an aesthetic dimension to virtue. In real life, as opposed to in celluloid, we are attracted to the good and repelled by the bad. Even the woman who says she prefers the archetypal 'bad boy' probably doesn't actually like it when he is bad toward her.
