A life of no regrets is unrealistic. However, this does not mean we should go to town, misbehaving at will. While it is true that human nature is fallible, when we rely on God to help us and guide us, we can live a fruitful and productive life, where we are constantly learning and adjusting our behavior as we go through life. That is an enabled life. A life of marvelous help from God. That is what we should aim for.
