This is really for a friend of mine (Joe), as one of his many goals in life is “World Domination”. I have found a web page that might help.
I particularly like this one:
Law 17 – Keep Others in Suspended Terror: Cultivate an Air of Unpredictability
Humans are creatures of habit with an insatiable need to see familiarity in other people’s actions. Your predictability gives them a sense of control. Turn the tables: Be deliberately unpredictable. Behavior that seems to have no consistency or purpose will keep them off-balance, and they will wear themselves out trying to explain your moves. Taken to an extreme, this strategy can intimidate and terrorize.
