Back then in my primary school days, when I started making use of "pen"; whenever I made a mistake, I would try hard to erase it before submitting to my teacher. Sometimes, I used chalk to clean my mistakes but it later reappeared when the chalk dust cleaned off. What I did then as a remedy was to use my saliva: it worked, but only to leave holes in my books. My teacher then would beat me for being outrageously dirty: but all I tried to do was to cover my errors.
On a good day, a kind hearted teacher who loved me so much, called me aside and said,
That sounded so strange to me, but He further explained:
I told him in protest; in the light of my confusion for such a strange principle that, I did not want people to see my mistake, but he laughed and said:
I never understood it until now.
Have you made some mistakes in life?
Don't expose yourself as a result of trying to cover your mistakes.
Better thing are ahead of you.
