Every successful piece of nonfiction should leave the reader with one provocative thought that he or she didn't have before. Not two thoughts, or five - just one. So decide what single point you want to leave in the reader's mind.
William ZinsserDonโt try to visualize the great mass audience. There is no such audienceโevery reader is a different person.
William ZinsserWriters are the custodians of memory, and that's what this chapter is about: how to leave some kind of record of your life and of the family you were born into.
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.
William ZinsserWriting is linear and sequential; Sentence B must follow Sentence A, and Sentence C must follow Sentence B, and eventually you get to Sentence Z. The hard part of writing isn't the writing; it's the thinking. You can solve most of your writing problems if you stop after every sentence and ask: What does the reader need to know next?
