Memoir isn't the summary of a life; it's a window into a life, very much like a photograph in its selective composition. It may look like a casual and even random calling up of bygone events. It's not; it's a deliberate construction.
William ZinsserDon't try to guess what sort of thing editors want to publish or what you think the country is in a mood to read. Editors and readers don't know what they want to read until they read it. Besides, they're always looking for something new.
William ZinsserThe best way to learn to write is to study the work of the men and women who are doing the kind of writing you want to do.
William ZinsserDon't hedge your prose with little timidities. Good writing is lean and confident. . . . Every little qualifier whittles away some fraction of the reader's trust. Readers want a writer who believes in himself and in what he is saying. Don't diminish that belief. Don't be kind of bold. Be bold.
