This is the point. Anyone who is properly introspective is already following the good advice given here. But how about the total ramrods one has to deal with on occasion, those people who are crazy and deluded, whose self-confidence totally exceeds their grasp of the subject matter? Blessed is the man who can say to his line manager "I won't deal with N.N. any longer, he is incompetent and unaware of it."
