Each human being has a vocation in life and a specific and unique calling. The Hasidic teacher Baruch of Medzibozh said that the world needs each and every human being because every person has the mission to make something perfect in this world. That mission is unique to the individual, who must fulfill his or her own personal destiny. Before his death, Rabbi Zusya of Hanipol said, "In the next world they will not ask me: 'Why were you not Moses?' They will ask me; 'Why were you not Zusya?' "
