Philosophy of life
 

• Scheme so as to discover his plans and the likelihood of their success. Rouse him, and learn the principle of his activity or inactivity. Force him to reveal himself, so as to find out his vulnerable spots. Carefully compare the opposing army with your own, so that you may know where strength is superabundant and where it is deficient.
• The wise man, takes his plan; the fool, takes his strength; the brave, takes his power; the timid, takes his care. For those of none of the above, use altogether.“Turn knowledge into wisdom, Dao models itself after nature, keep to the center, all good things take time.”​As time passes, make rule accordingly, change according to things, adjust according to people.
