Learn from Mistakes - Real life Moral Story for Children

Thomas Edison tried two thousand different materials in search of a filament for the light bulb. When none worked satisfactorily, his assistant complained, “All our work is in vain. We have learned nothing.” 

Edison replied very confidently, “Oh, we have come a long way and we have learned a lot. We now know that there are two thousand elements which we cannot use to make a good light bulb.”

Edison's assistant was surprised about the positive thinking of his master.

Moral : Always, there will be plenty of good things to learn from a failure.
