You cannot worry about upsetting every person you come across, but you must be selectively cruel. If your superior is a falling star, there is nothing to fear from outshining him. Do not be merciful—your master had no such scruples in his own cold-blooded climb to the top. Gauge his strength. If he is weak, discreetly hasten his downfall: Outdo, outcharm, outsmart him at key moments. If he is very weak and ready to fall, let nature take its course. Do not risk outshining a feeble superior—it might appear cruel or spiteful. But if your master is firm in his position, yet you know yourself to be the more capable, bide your time and be patient. It is the natural course of things that power eventually fades and weakens. Your master will fall someday, and if you play it right, you will outlive and someday outshine him.
