The letter is one of the earliest and most widely practiced forms of the personal essay: It tells a story about the author's life; it poses questions; and, perhaps most important, it's a way of connecting to a reader. Write a letter to someone you know, keeping the basic tenants of the personal essay in mind. The letter should be about you, but should also somehow address a larger question or idea. For inspiration, check out Helene Hanff's 84, Charing Cross Road (Grossman, 1970), a collection of letters that documents her years-long correspondence and relationship with the owners of Marks & Co., a bookstore in London.
