Today, I'll bring you rules 3 and 4 from the 48 laws of power.
3) Conceal your intentions
Keep people off balance and in the dark by never revealing the purpose behind your actions. If they have no clue what you are up to, they cannot prepare a defence. Guide them far enough down the wrong path, envelope them in enough smoke and by the time they realize your intentions, it will be too late.
4) Always say less than necessary
When you are trying to impress people with words, the more you say the more common you appear and the less in control. Even if you are saying something banal, it will seem original if you make it vague, open ended and sphinxlike. Powerful people impress and intimidate by saying less. The more you say, the more likely you are to say something foolish.
