From the book "The Art of War" written by the great Chinese strategist Sun Tzu, some 2,500 years ago:
On Tactical Dispositions
"The good fighters of old first put themselves beyond the possibility of defeat, and then waited for an opportunity of defeating the enemy."
"To secure ourselves against defeat lies in our own hands, but the opportunity of defeating the enemy is provided by the enemy himself."
On Weak Points And Strong
"Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted."
"Therefore, the clever combatant imposes his will on the enemy, but does not allow the enemy's will to be imposed on him."
