Hello @pelon53 sir,
Your mother rightly said that mistakes are for the wise. And this is the reality that if we don't make mistakes we can learn nothing. I think it is very useful for the improvement of our life.

Sir you have made a realistic point that it is a great school because we learn from it. So by utilizing this education we are able to achieve success in our life.

Lastly, thank you very much for inviting me. I read and enjoy your publications regularly. I wish you all the best in the competition.
