There's a point beyond which one doesn't care to worry anymore- it's not defeat or despair but the strength and courage to accept and challenge - what life has strewn on the way
this is the essence of self-understanding of stoicism and of Taoism in letting go in not seeking and non-striving with the self in conscious emptying
this then becomes the self unbreakable : life has been overcome and the individual enters into the realm of complete bliss and freedom
