One mark of a great soldier is that he fight on his own terms or fights not at all.

Generally, management of many is the same as management of few. It is a matter of organization. And to control many is the same as to control few. This is a matter of formations and signals.

We cannot enter into alliance with neighbouring princes until we are acquainted with their designs. We are not fit to lead an army on the march unless we are familiar with the face of the country - its mountains and forests, its pitfalls and precipices, its marshes and swamps. We shall be unable to turn natural advantages to account unless we make use of local guides.

The value of time, that is of being a little ahead of your opponent, often provides greater advantage than superior numbers or greater resources.

Attack like the Fire and be still as the Mountain

You can prevent your opponent from defeating you through defense, but you cannot defeat him without taking the offensive.

Victory is reserved for those who are willing to pay its price.
