“Change is what political leadership is about.”

From 1980s onwards, Only Integrity is Going to Count (1983)
Context: When I was born, humanity was 95 per cent illiterate. Since I've been born, the population has doubled and that total population is now 65 per cent literate. That's a gain of 130-fold of the literacy. When humanity is primarily illiterate, it needs leaders to understand and get the information and deal with it. When we are at the point where the majority of humans them-selves are literate, able to get the information, we're in an entirely new relationship to Universe. We are at the point where the integrity of the individual counts and not what the political leadership or the religious leadership says to do.

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.
