There is an intelligent way to eat a live frog - I just don't know what it is.

You can ensure the success of your attacks if you only attack places that are undefended. You can ensure the safety of your defense if you only hold positions that cannot be attacked. Therefore, that general is skillful in attack whose opponent does not know what to defend; and he is skillful in defense whose opponent does not know what to attack.

The supreme excellence is not to win a hundred victories in a hundred battles. The supreme excellence is to subdue the armies of your enemies without having to fight them.

He who wishes to fight must first count the cost

The skillful leader subdues the enemy's troops without any fighting.

Weak leadership can wreck the soundest strategy

Know thy self, know thy enemy. A thousand battles, a thousand victories.
