Sir, what you said "whoever has given up his uniqueness, has wasted his life"....But was just thinking if thats really possible to give up on our uniqueness..Many of us do try to put in our feet in others role and we start enjoying it.. Following an idol is not bad .. children want to be like their parents.. its always good to adopt good things from others that adds to the persona of our own.Every individual is born unique and anything he picks up from others is offcourse adding into his personality for a new charm which he carries it with his own way, which still looks different on him and this keeps his uniqueness at place.
But offcourse going for imitating , copying to be a carbon copy is foolishness that fails .. The original is always preferred and appreciated over duplicate .
