Though Sartre's conclusion seems to be that being diminishes before nothingness since consciousness is probably based more on spontaneity than on stable seriousness, he contends that any person of a serious nature is obliged to continuous struggle between:
a) the conscious desire for peaceful self-fulfillment through physical actions and social roles—as if living within a portrait that one actively paints of oneself.
b) the more pure and raging spontaneity of no thing consciousness, of being instantaneously free to overturn one's roles, pull up stakes, and strike out on new paths.
