The most important thing about becoming a manager, is to remember that companies are not kingdoms. You do not "rule" people - if you're good, you inspire, motivate and shepard them.

Although I have a Bachelor and Masters degrees, my greatest "training" for management came from my years of playing semi-pro ice hockey. There you learn that although you may have some great skills - lets say shooting the puck - someone else has to make the great play to pass you the puck to shoot. And someone else had to make the great defensive play to turn the puck over to your team.

Business is something like that. If you try to "rule" like you are the only player on the ice, good luck. You will be very ineffective in a short matter of time. On the other hand, if you learn that the members of your team will do great things, merely part of the greater whole, you will come to realize that you, and your team are a unit, and no one of you (you included) is any better than anyone else. Its the complimentary skills on your team that make the team, and the members great.

Look at any team sport you like - and look at any hero - he or she is only as good as those around them. David Becham could not score a goal without teammates to pass him the ball. Kobe Bryant does not play on the court alone - he needs teammates to feed him the ball.

Never let your head fall into the "kingdom" concept of management, because that simply becomes a "dictatorship" in a short time and we all know what generally happens to dictatorships.
