Speak as little as possible about oneself
Take care of one's personal matters
Avoid curiosity
Do not meddle in the affairs of others
Accept contradictions with good humor
Do not focus on the faults of others
Accept reproach, even if undeserved
Yield to the will of others
Accept insults and abuse
Accept feeling uncared for, forgotten, despised
Be courteous and sensitive, even if someone provokes you
Do not try to be admired and loved
Do not hide behind one's own dignity
Yield in arguments, even if one is right
Always choose what is most difficult
