Law 17
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. –Robert Greene, The 48 Laws of Power (review)
