I Would Surmise that Sometimes an Individual can have such a hard life that they Become Broken and through that Brokenness they Become Rejuvenated as their Only hope to succeed relies on their Inner Strength. When there's nothing and nobody else left to Rely on. It is In those Dark Moments of Life when they Rise above the Totality of their Misfortune or Failure, that they then find the Meaning of Life.. to serve not just for self but also Humanity, which brings the Greatest Fulfillment and Joy knowing that their Determination to Survive, regardless of Situation is Paramount to their own existence and Well-being .
