Never underrate the boss! The boss may look illiterate. He may look stupid. But there is no risk at all in overrating a boss. If you underrate him he will bitterly resent it or impute to you the deficiency in brains and knowledge you imputed to him.
Peter DruckerThe great mystery isn't that people do things badly but that they occasionally do a few things well. The only thing that is universal is incompetence. Strength is always specific! Nobody ever commented, for example, that the great violinist Jascha Heifetz probably couldn't play the trumpet very well.
Peter DruckerThe problem in my life and other people's lives is not the absence of knowing what to do but the absence of doing it.
