The document tells a story about a boy who has a difficult temper. His father gives him nails and tells him to hammer one into the fence each time he loses his patience. The first day he hammers 37 nails. Over time, as he learns to control himself, fewer nails are hammered each day. Eventually he is able to control his temper completely and removes all the nails from the fence. His father tells him that while the nails are gone, the holes they left remain, just as hurtful words can leave wounds even if you apologize. The document concludes with various proverbs about friendship, love, mistakes, dreams and more.
