In ancient times, a King had a boulder placed on a roadway. Then he hid himself and watched to see what people would do. Some simply walked around it. Many complained, but none did anything about getting the stone out of the way.
Then a peasant came along carrying a load of vegetables. He tried to move the stone to the side of the road. After much pushing and straining, he finally succeeded. 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 of us struggle to understand. In the words of Napoleon Hill, “Every adversity, every failure, every heartache carries with it the seed of an equal or greater benefit.”
