To come to know your enemy, first you must become his friend, and once you become his friend, all his defences come down. Then you can choose the most fitting method for his demise.
Ieyasu TokugawaThe strong manly ones in life are those who understand the meaning of the word patience. Patience means restraining one's inclinations. There are seven emotions: joy, anger, anxiety, adoration, grief, fear, and hate, and if a man does not give way to these he can be called patient. I am not as strong as I might be, but I have long known and practiced patience. And if my descendants wish to be as I am, they must study patience.
