"Be Content With Your Lot"
Context: Some scholars think that Aesop was a contemporary of Homer, and the first evidence of a fable comes from about this time or a little later from the time of Hesiod, who repeated the fable of the eagle and the nightingale. Certainly in this fable we find the older reverence of the gods, for Hera (or Juno) gives the peacock better advice than the peacock received from the jay of another tale.
A peacock once placed a petition before Juno desiring to have the voice of a nightingale in addition to his other attractions; but Juno refused his request. When he persisted, and pointed out that he was her favorite bird, she said:"Be content with your lot; one cannot be first in everything."
