As a person who has never had much power, I have nevertheless made my study of it. I have tried to take a clinical "all over" view of it, but I must confess that all my best views have been of its belly.
Here are the first two rules of power:
1. To rule power effectively one must disregard the opinions of others.
2. If one disregards the opinions of others one cannot rule power effectively.
I never said it was easy.
