Here is the cold, hard truth: You simply can't set out to write a story that tackles a range of broad topics all at once. When it comes to writing a story that people will want to read, you have to focus. You have to choose. You have to get really specific. As the great E. B. White said, “Don't write about Man; write about a man.” In the case of memoir, this could be translated into, "Don't write about your whole life; write about a key moment in it."
