I think it is not easy to be a manager, because he has to have lots of skills which are not that easy to handle with. In everyday working life, mistakes happen and even if it were one of the team members, the manager has to take the responsibility and accept the blame. Great managers are forever trying to catch their people doing something right, and congratulating them on it. Managers who regularly give praise are in a much stronger position to criticise or reprimand poor performance. Another skill of a manager is, that he has to judge on merit. A great deal more difficult than it sounds. It is impossible to divorce your feelings about someone- whether you like or dislike them- from how you view their actions. Further great managers see strengths, in themselves as well as in other people, as things to be built on, and weakness as something to be accommodated, worked around, and if possible, eliminated. At least and what I think is the most important skill is, that he has to make himself redundant. The team has to work also well, even if he is absent. The work does not depend on him.
