A good manager is a man who isn't worried about his own career but rather the careers of those who work for him. My advice: Don't worry about yourself. Take care of those who work for you and you'll float to greatness on their achievements.
A good manager doesn't try to eliminate conflict; he tries to keep it from wasting the energies of his people. If you're the boss and your people fight you openly when they think that you are wrong -- that's healthy.
The Trojans lost the war because they fell for a really dumb trick. hey, there's a gigantic wooden horse outside and all the Greeks have left. Let's bring it inside! Not a formula for long-term survival. Now if they had formed a task force to study the Trojan Horse and report back to a committee, everyone wouldn't have been massacred.. Who says middle management is useless?
We are now in the third stage of the industrial revolution. The first involved machines which extended human muscle; the second used machines to extend the human nervous system (radio, television, telephones); the third is now utilizing machines which extend the human mind-computers. About half of all service workers (43 percent of the labor force by 2000) will be involved in collecting, analyzing, synthesizing, structuring, storing, or retrieving information... By 1995, 80 percent of all management will be knowledge workers.
