A very hungry jackdaw is sitting in the tree. This tree has no fruit. It is not the season for the fruit. But he is waiting. He hopes that the fruit will grow. When a fox sees him sitting so long and learns the reason of his doing so, he says to him, “You are cheating yourself; you are having a hope, but this hope is too strong for you.” He laugh at the jackdaw and says again: “This hope will never reward you with enjoyment.”
Despair is the price one pay for setting oneself an impossible aim.
-Graham Greene
