Creative writing: NEVER PUT TOO MUCH TRUST IN FRIENDS, LEARN HOW TO USE ENEMIES.

Be wary of friends they will betray you more quickly, for they are easily aroused to envy. They also become spoiled and tyrannical. But hire a former enemy and he will be more loyal than a friend, because he has more to prove. In fact, you have more to fear from friends than from enemies. If you have no enemies, find a way to make them.

Although it is generally best not to mix work with friendship, there are times when a friend can be used to greater effect than an enemy. A man of power, for example, often has dirty work that has to be done, but for the sake of appearances it is generally preferable to have other people do it for him; friends often do this the best, since their affection for him makes them willing to take chances. Also, if your plans go awry for some reason, you can use a friend as a convenient scapegoat. This “fall of the favorite” was a trick often used by kings and sovereigns: They would let their closest friend at court take the fall for a mistake, since the public would not believe that they would deliberately sacrifice a friend for such a purpose. Of course, after you play that card, you have lost your friend forever. It is best, then, to reserve the scapegoat role for

someone who is close to you but not too close.
Finally, the problem about working with friends is that it confuses the boundaries and distances that working requires. But if both partners in the arrangement understand the dangers involved, a friend often can be employed to great effect. You must never let your guard down in such a venture, however; always be on the lookout for any signs of emotional disturbance such as envy and ingratitude. Nothing is stable in the realm of power, and even the closest of friends can be transformed into the worst of enemies.
