Sanyasi @@'s Key Ideas from The 48 Laws Of Power
by Robert Greene

Keep people off balance and in the dark by never revealing the purpose behind your actions. If they have no clue what you are upto, they cannot prepare a defence. Guide them far enough down the wrong path, envelop them in enough smoke, and by the time they realize your intentions, it will be too late.

When you are trying to impress people with words, the more you say, the more common you appear, and the less in control. Powerful people impress and intimidate by saying less. The more you say, the more likely you are to say something foolish.
