The most important fight is against the enemy within
Pretend to be weak, that he may grow arrogant.
Attack him where he is unprepared, appear where you are not expected.
He who knows when he can fight and when he cannot, will be victorious.Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win.
If ignorant both of your enemy and yourself, you are certain to be in peril.
Know your enemy and know yourself and you can fight a hundred battles without disaster.
The opportunity to secure ourselves against defeat lies in our own hands, but the opportunity of defeating the enemy is provided by the enemy himself.
To fight and conquer in all our battles is not supreme excellence; supreme excellence consists in breaking the enemy’s resistance without fighting.
Opportunities multiply as they are seized.
You have to believe in yourself.
