There once lived a little boy with a bad temper. One day, his father decided to hand him a bag of nails and told him that every time he lost his temper he had to hammer a nail into the fence. On just the first day, he hammered 37 nails into the fence!
The boy began to control his temper over the next few weeks, and the number of nails he was hammering into the fence slowly decreased!
He discovered it was easier for him to control his temper than to hammer those nails into the fence.
Finally, the day arrived when the boy didn’t lose his temper at all! He told his father the news and the father suggested that the boy should now pull out a nail every day he kept his anger under control .
The days passed and the young boy was finally able to tell his father that all the nails were gone. The father took his son by the hand and led him to the fence: “you have done well, my son but look at the holes in the fence. The fence will never be the same. When you say things in anger, they leave a scar just like this one. You can put a knife in man and draw it out, it won’t matter how many times you say I’m sorry, the wound is still there.”
