In contests of strategy it is bad to be led about by the enemy. You must always be able to lead the enemy about.

When your opponent is hurrying recklessly, you must act contrarily and keep calm. You must not be influenced by the opponent.

Anger. Control your anger. If you hold anger toward others, they have control over you.Your opponent can dominate and defeat you if you allow him to get you irritated.

Never depart from the way of martial arts.

You should not have a favourite weapon. To become over-familiar with one weapon is as much a fault as not knowing it sufficiently well.

The way is in training.

Immature strategy is the cause of grief.
