In fighting and in everyday life you should be determined though calm. Meet the situation without tenseness yet not recklessly, your spirit settled yet unbiased. An elevated spirit is weak and a low spirit is weak. Do not let the enemy see your spirit.

The only reason a warrior is alive is to fight, and the only reason a warrior fights is to win
You can only fight the way you practice
To win any battle, you must fight as if you are already dead
