This inspired me, and I believe it would be useful to you, so I had to share.
When I started using pen in my primary school, and I make a mistake, I would try hard to erase it before submitting to my teacher.
Sometimes i would use the chalk to clean my mistake, but re-appeares later. So I tried out erasing with my saliva. it worked, but only to leave holes in my books.
My teacher then would punish me for being outrageously dirty, But all I tired to do was to cover my error.
One day, a kind hearted teacher who loves me so much called me aside and he said; " anytime you make a mistake, just cross it and move on". He said further ; " trying to erase your mistake would only damage your book to nothing".
I told him in protest that I don't want people to see my mistake!. But my lovely teacher laughed and said; "trying to erase your mistake will make more people know about your mess and the stigma is for life".
Now have you made some mistake in life?
