Many things in life are contrastingly classified. What is great once can easily be overshadowed by with what is extraordinary; the extraordinary with the fabulous, and the fabulous with the marvelous. If personal achievement is left to such disparity, dissatisfaction becomes the overriding emotion, like eating while desiring the dish next table. So it is healthy & sensible to cap once success with a set (and reachable) goal, each light shining on its respective spot. A fulfilled life is singlehandedly focused; it doesn’t enter into confusion by comparison. Paul hammered on this in one of his letters: “Make it your ambition to lead a quiet life, to mind your own business” (1Th 3:11)
