Nature abhors people. Changing things is central to leadership, and changing them before anyone else does is creative leadership. The less work an organization produces, the more frequently it reorganizes. Whatever happens, look as if you intended it to happen. At any particular time, there are more horses' asses in the world than there are horses.
Teamwork is essential.
It allows you to blame someone else. An expert is one who knows more and more about less and less until he knows absolutely everything about nothing. You can make something foolproof, but you can't make it damnfoolproof. Anyone who is popular is bound to be disliked. Assumption is the mother of all screwups.
