One eighteenth-century rabbi put it this way: “A person should always carry two slips of paper, one in each pocket. On one it should be written ‘The world was created for my sake,’ and on the other it should say ‘I am but dust and ashes.’ “14 On days when we feel discouraged and worthless, we should read the first one. On days when we’re consumed with pride and our own self-importance, we should read the other.
