Act after having made assessments. The one who first knows the measure of far and near wins - this is the rule of armed struggle.

Carefully compare the opposing army with your own, so that you may know where strength is superabundant and where it is deficient.

According to my assessment, even if you have many more troops than others, how can that help you to victory?

Attack the enemy's strategy.

Of all those in the army close to the commander, none is more intimate than the secret agent.

A leader leads by example not by force.

Be where your enemy is not.
