The loss of any army is always caused by underestimating the enemy. Therefore gather information and watch the enemy carefully.

Battles are not won by strength alone!

Detach from emotions and desires; get rid of any fixations.

To overcome the intelligent by folly is contrary to the natural order of things; to overcome the foolish by intelligence is in accord with the natural order. To overcome the intelligent by intelligence, however, is a matter of opportunity.

What loss is there in dignity, what worry is there of failure?

Opportunistic relationships can hardly be kept constant. The acquaintance of honorable people, even at a distance, does not add flowers in times of warmth and does not change its leaves in times of cold: it continues unfading through the four seasons, becomes increasingly stable as it passes through ease and danger.

Good generals select intelligent officers, thoughtful advisors, and brave subordinates. They oversee their troops like a fierce tiger with wings.
