One day a king goes to a
faraway place in his country. When he comes back, his feet hurt a lot. "There
are too many small stones on the roads. They hurt my feet. Cover every road
with leather," he tells his men. Of course, it will cost a lot of money. One
of his men is very smart. He tells the king, "Why not cut a little piece
of leather to cover your feet?" The king is surprised, but he agrees to
the man's idea. He asks his men to make a pair of leather shoes for him.
This may not have been the
real beginning of leather shoes. But it teaches us a lesson of life: If you
want to make this world a happy place to live in, the best way is to change
yourself, not the world.
