"Distrust friends, they are usually the first to betray you as they easily fall prey to envy, they also tend to become disrespectful and tyrants. On the other hand, employ someone who has been your enemy and they will be more loyal than a friend as you will have to make greater efforts to demonstrate your allegiance. The truth is that you should fear your friends more than your enemies... If you do not have enemies, find a way to create them".
