I seem to want to share this little story with everyone I meet lately:
Rabbi Zusya, when he was an old man, said, “In the coming world, they will not ask me: “Why were you not Moses?”
They will ask me: “Why were you not Zusya?”
So let us all be reminded: In the final reckoning, it will not matter whether you were Moses or whoever you compare yourself to. In the final reckoning, what will matter is whether you were yourself.
"Why were you not Zusya?"
(This lovely story is in Parker J. Palmer’s Let Your Life Speak, a book that is dear to me.)
