There is no other way to guard yourself against flattery than by making men understand that telling you the truth will not offend you. - Niccolò Machiavelli

Time sweeps everything along and can bring good as well as evil, evil as well as good.

When evening has come, I return to my house and go into my study. At the door I take off my clothes of the day, covered with mud and mire, and I put on my regal and courtly garments; and decently reclothed, I enter the ancient courts of ancient men, where, received by them lovingly, I feed on the food that alone is mine and that I was born for. There I am not ashamed to speak with them and to ask them the reason for their actions; and they in their humanity reply to me. And for the space of four hours I feel no boredom, I forget every pain, I do not fear poverty, death does not frighten me. I deliver myself entirely to them.

There is a general note to be noted here: People should either be caressed or crushed. If you do them minor damage they will get their revenge; but if you cripple them there is nothing they can do. If you need to injure someone else, do it in such a way that you do not have to fear their vengeance.
