The persona is misconceived by too many as a mask, or a suit of armor - a barrier to hide behind. In reality it's far more like a martial art. It is a matter of self-knowledge: learning one's capacities, choosing which strengths to rely on and developing them into knowing, in practice. Being always one's self on the way to one's best self, never getting there.
Point is: I digress. But a carefully-constructed self-concept is a pretty sweet deal.
