Remember that you are a son. What does being a son require? Consider everything you own as belonging to your father. Obey him in everything. Never criticize him to others. Never say or do anything that hurts him. Give way to him in all things. Work with him as much as you can. Also remember that you are a brother. What does being a brother require? Make compromises. Be easily convinced. Speak well of your brother. Never fight him over things outside your control. Give those things up freely. This way you get a bigger share of what is within your control. Think about it: you give up a piece of lettuce or a chair, and in return you gain good character. What a great trade.
After this, remember that you are a son. What does this character promise? To consider that everything which is the son's belongs to the father, to obey him in all things, never to blame him to another, nor to say or do anything which does him injury, to yield to him in all things and give way, co-operating with him as far as you can. After this know that you are a brother also, and that to this character it is due to make concessions; to be easily persuaded, to speak good of your brother, never to claim in opposition to him any of the things which are independent of the will, but readily to give them up, that you may have the larger share in what is dependent on the will. For see what a thing it is, in place of a lettuce, if it should so happen, or a seat, to gain for yourself goodness of disposition. How great is the advantage.
