Some years ago, I heard the story of a high school history teacher who knew this same secret. On one particularly fidgety and distracted afternoon she told her class to stop all their academic work. She let her students rest while she wrote on the blackboard a list of the names of everyone in the class. Then she asked them to copy the list. She instructed them to use the rest of the period to write beside each name one thing they liked or admired about that student. At the end of class she collected the papers.
Weeks later, on another difficult day just before winter break, the teacher again stopped the class. She handed each student a sheet with his or her name on top. On it she had pasted all twenty-six good things the other students had written about that person. They smiled and gasped in pleasure that so many beautiful qualities were noticed about them.
