Jay's Laws of Leadership
#Changing things is central to leadership, and changing them before anyone else is creativeness.
#To build something that endures, it is of great importance to have a long tenure in office-to rule for many years. Quick success can be achieved in a year or two, but nearly all great tycoons have continued their building much longer.
