Things which matter most must never be at the mercy of things which matter least. - Stephen Covey

Effective leadership is putting first things first. Effective management is discipline, carrying it out.

If two people have the same opinion, one is unnecessary. It’s not going to do me any good at all to communicate with someone else who sees only the old woman also. I don’t want to talk, to communicate, with someone who agrees with me; I want to communicate with you because you see it differently. I value that difference.

And to change ourselves effectively, we first had to change our perceptions.
