从前,有一个脾气很不好的孩子,他的爸爸给了他一袋钉子,告诉他:“每次发脾气或者跟人吵架以后,就在院子的篱笆上钉一颗钉子。”第一天,这孩子钉了37根钉子。后面的几天,他学会了控制自己的脾气,每天钉的钉子逐渐减少了。他发现,控制自己的脾气,实际上比钉钉子容易得多。 Once upon a time, there was a child with a bad temper. His father gave him a bag of nails and told him: “Each time you lose your temper or quarrel with people, you nail a nail in the fence of the yard.” The child nailed 37 nails. In the following days, he learned to control his temper, and the number of nails nailed every day gradually decreased. He found that controlling his temper is actually much easier than nailing nails.
