The key to Jewish life is awareness.
The essential point of Judaism is to make us aware of our actions and how they impact others. Consider the sage Hillel's words to the prospective convert, in response to the latter's challenge to explain all of Judaism while standing on one leg: "Do not do unto others what is hateful unto you. All the rest is commentary. Now go and learn it."
Hillel teaches us that the central tenet of Jewish life and learning is that we should always consider how our actions affect others, and devote a lifetime to studying the details. Now go and learn it, indeed.
