Rabbi Zusya said that on the Day of Judgment, God would ask him, not why he had not been Moses, but why he had not been Zusya.

I would rather be what God chose to make me than the most glorious creature that I could think of; for to have been thought about, born in God’s thought, and then made by God, is the dearest grandest, and most precious thing in all thinking.
George Macdonald

I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.
Psalm 139:14
