The Peacock's Complaint

 A peacock was very unhappy with his ugly voice, and he spent most of his days complaining about it.

     "It is true that you cannot sing," said the fox, "But look how beautiful you are!"
     "Oh, but what good is all this beauty," moaned the dishearten bird, "with such an unpleasant voice!"

    "Oh hear," said the fox, "Each one has it's special gift. You have such beauty, the nightingale has his song, the owl has his eyes, and the eagle his strength. Even if you had a eloquent voice, you would still complain about another thing."

Do not envy the gifts of others. Make the most of your own.
