In ancient times, a king had a boulder placed on a roadway.
Then he hid 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 no one did anything about getting the stone out of the way.
Then a peasant came along carrying a load of vegetables.
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 of us never understand: Every obstacle presents an opportunity.
