Once upon a time there was a painter who had just finished his course from a great painter. He wanted to assess his skills, so he decided to display one of his best works on a busy street.
He put his painting at a busy street-crossing. And below it a board read — Gentlemen, I have painted this piece. Since Im new, I might have made some mistakes in my work. 65
When he came back in the evening to collect his painting, he was completely shocked to see that the whole painting was filled with crosses.
66He burst into tears and said sadly, Im useless and if this is what I have learned to
paint, Im not worth teaching.
The master smiled and suggested, My son, I will prove that you are a great artist. The master told him, Just paint the same painting once again and give it to me.
Then they went to the same street the next morning and displayed the same painting. The master took out another board which read — Gentleman, I have painted this piece. Since Im new, I might have made some mistakes. I have put a box with colors and brushes just below. Please do
me a favor. 67The master and the young painter went back home.
They visited the place in the evening. The young painter was surprised to see that actually there was not a single correction done! 68If you want to help people improve their behaviors, it is worth investing your effort in learning how to help people change their behaviors, attitudes and skills.
