'It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles;
If you do not know your enemies but do know yourself, you will win one and lose one;
If you do not know your enemies nor yourself, you will be imperiled in every single battle.'

Sun Tzu - Art of War

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

Sun Tzu - Art of War

'What the ancients called a clever fighter is one who not only wins, but excels in winning with ease.'
