In ancient times, a king had a boulder placed on a roadway. Then he
 hid  himself and watched to see if anyone would remove the huge rock.
  Some of the king's wealthiest merchants and courtiers came by and
simply  walked around it.  Many loudly blamed the king for not keeping the roads clear, but
 none did anything about getting the big stone out of the way. Then a
 peasant came along carrying a load of vegetables.  On approaching
the  boulder, the peasant laid down his burden and tried to move the
 stone to  the side of the road.

  After much pushing and straining, he finally succeeded.
  As the peasant picked up his load of vegetables, he noticed a purse
  lying in the road where the boulder had been.
  The purse contained many gold coins and a note from the king
  indicating that the gold was for the person who removed the
  boulder from the roadway.  The peasant learned what many
  others never understand.  Every obstacle presents an
  opportunity to improve one's condition.
