Learning from Mistakes

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 know that there are two thousand elements which we cannot use to make a good light bulb.”

Moral: We can also Learn from Our Mistakes.
