Build your opponent a golden bridge to retreat across.

Attack where he is unprepared; sally forth when he does not expect you.

Concentrate your energy and hoard your strength.

Rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him

Unhappy is the fate of one who tries to win his battles and succeed in his attacks without cultivating the spirit of enterprise, for the result is waste of time and general stagnation.

Winning isn't enough. The acme of all skill is to defeat your enemy before taking the field.

I will be able to forecast which side will be victorious and which defeated.
