Leadership is not a position; it's an activity. Our tradition calls us to exercise leadership even and especially when it's difficult or uncomfortable. Stories both personal and traditional help illustrate this them.
The Outcast is the Messiah
Parashat Tazria-Metzora deals famously with the disease known as tzaraat, translated (not entirely accurately) as leprosy. The image of the isolated leper is a familiar one, but the Torah insists that the reintegration is the ideal. No one should be separated forever, and it is upon us to go to the margins of society to reach out to those who have been cast off--even if for good reason--to welcome them back to the whole the moment they're ready to return.
