A life well lived does not mean a life without mistakes. It means making mistakes in the right direction. A famous Talmudic passage re-read by my teacher Mordechai Lainer of Izbica says roughly as follows “One cannot follow the direction of one’s life until one first fails in pursuing that very direction.” Or in another passage, the Talmud itself writes, “The wicked falls once and does not rise, the Master falls seven times and rises each time again”.
Failure and falling is part of the process. Our response-ability is is a constant process of Teshuva.  Teshuva means literally to return.
In the language of R. Kuk,
“Man has forgotten himself, When he remembers himself he must gather the fragments of his soul from their exile, he must return to himself, to his essential I, and when he returns to himself, at that very moment, he will have returned to God.”
