Pirket Avot mention is is not our duty to finish the work, neither can we desist from the work. We interpret this line to mean working towards social justice. We live in a time when we are bombarded with injustices all around us and while it is easy to criticize the fsilure for everyday lapses in confronting injustice, does this actually help us reach a more just society? How do our Sages help us do triage in the world around us, and where would they tell us to turn our attention to first?
