People will sometimes suppose that only big drama can make an interesting memoir. Of course, there are many readers who require constant titillation if they are to remain reading.

Some would-be memoir-writers get discouraged by the ordinariness of their lives. Yet, I have found that almost everyone I have had a serious conversation with about memoir writing had enough happen in their lives to fashion an interesting memoir.
