We compare ourselves with others. You can imagine the results already. Either you are prompted to feel smug and proud because your strengths outweigh his weaknesses—or, more often, you begin to feel threatened, inferior, and blue because you fail to measure up. Striving to emulate a self-imposed standard, you begin to slide from the pleasant plateau of the real you to the sinking sands of I don't know who. This sometimes leads to extreme role-playing where you try every way to adapt and alter your portrait to fit into someone else's frame. In simpler terms, you've pawned your real personality for a phony disguise.
