If you must hurt a man,do it so brutally you need not fear hisnrevenge.
Even a mouse three holes.
If you allow your enemies---or friends---to thinkthey are your equals,
they will immediately think they are your superiors.
Don't try to change your enemies,just try to control them.
Know where they are,what they think,and who they trust.
Promise little;deliver much.
When you are angry,close your mouth---and open your eyes.
But don't angry,get even.
State to yourself what you be;then do what is necessary.
Never understimate these three things:(1)your opponent's abilities;
(2)your opponent's cunning;(3)your opponent'sgreed.
Never overstimate them either.
He who answers for another pays the bill.
The only way to keep a secret is to say nothing.
Overvalue negative estimates of your propects in any venture by two,
Undervalue positive estimates by half.
