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.”
Dear Neelimaji and others,
Don't give up...... With your mistakes, now you know where the mistake was and the reason behind it. So obviously, you should not do the same mistake in future like Thomas Edison not used the same two thousand elements for making a filament bulb.
