Regard your soldiers as your children, and they will follow you into the deepest valleys; look on them as your own beloved sons, and they will stand by you even unto death.
Know thy self, know thy enemy. A thousand battles, a thousand victories.
If you know the enemy and know yourself you need not fear the results of a hundred battles.
Let your plans be dark and as impenetratable as night, and when you move, fall like a thunderbolt.
Opportunities multiply as they are seized.
Can you imagine what I would do if I could do all I can?
Pretend inferiority and encourage his arrogance.
