Opportunities multiply as they are seized.

To fight and conquer in all our battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.

Know the enemy and know yourself.

Build your opponent a golden bridge to retreat across.

To perceive victory when it is known to all is not really skilful... It does not take much strength to lift a hair, it does not take sharp eyes to see the sun and moon, it does not take sharp ears to hear the thunderclap.

If you know neither the enemy nor yourself, you will succumb in every battle

In war, practice dissimulation and you will succeed.
