Writing 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?

William ZinsserAll your clear and pleasing sentences will fall apart if you don't keep remembering that writing is linear and sequential, that logic is the glue that holds it together, that tension must be maintained from one sentence to the next and from one paragraph to the next and from one section to the next, and that narrative - good old-fashioned storytelling - is what should pull your readers along without their noticing the tug.
