Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE FOX AND THE MAN COUNTING THE WAVES
Aesop tells this story. A certain man was sitting on the beach counting the
waves as they broke against the shore. When he lost count of the waves he got
angry and frustrated. A sly fox then approached the man and said, 'Good sir,
what is the point of getting angry about the waves that have already gone by?
You need to just put them out of your mind and pick up counting again where
you left off!'
