Use, but don’t abuse, hidden intentions, and above all, don’t reveal them
All art must be concealed, for it rouses suspicion, especially hidden intentions, which are hateful. Deceit is common, so be on your guard. But hide your caution from others, so as not to lose their confidence. When it becomes known, caution offends others and provokes vengeance, awakening unimagined evils. A reflective way of doing things will give you a great advantage. Nothing provides more food for thought. The greatest perfection of an action depends upon the mastery with which it is carried out.
