“Even in the common affairs of life, in love, friendship, and marriage, how little security have we when we trust our happiness in the hands of others!”
“The best day of your life is the one on which you decide your life is your own. No apologies or excuses. No one to lean on, rely on, or blame. The gift is yours - it is an amazing journey - and you alone are responsible for the quality of it. This is the day your life really begins.”
One of the greatest lessons of the Torah is personal responsibility [see Avodah Zara 17b about Eliezer ben Durdaya]. When doing tshuva we must take upon ourselves full responsibility for our actions, past, present and future. This is EMPOWERING. It means that we don't have to entrust our happiness and well-being in the hands of others.
Just us and Hashem.
