Once there was a boy with a bad temper, his father gave him a bag of nails and told nailing a nail sticks in the yard fence every time he lost his temper or disagreements with others.on the first day he was nailing 37 rods on the fence. in the following weeks he learned to restrain himself, and the number of spikes are worn down from day to day. He found that the restraint is easier than tacking on the fence.
Finally the day arrived when she did not need anymore nail and a nail was happily conveyed it to his father.
