Anyone who even thinks about wanting to write should have this book on the nighttable, or within easy reach of brief periodic readings. There are no opinions here, only straightforward, "this is how it is" rules and anecdotes of English instruction. The underlying point, like all good English books, is that there really is no new way to say, "it is," but rather that certain words and expressions fade out and must eventually be replaced. The English language, like all human languages, change over time, but some standards must remain.
This book can be read cover to cover in less than four hours by an "average" reader, and after several more passes, the what was once forgotten rule becomes a part of memory. It is enjoyable to read because there are no tests. It was also a definite positive factor to my last book, "Confessions of a Reformed Road Warrior," becoming better than was the first few drafts. Before I sat down at my computer for a writing session, I would have the cadence of "The Elements of Style" going through my internal writing filters. This book, like a few others which are noteworthy, must be a mainstay on the bookshelf of any would-be author, word processor or office supervisor.
Get it, read it, memorize it. Learn the basics before you move on to more complex pieces of writing. You will become more confident for having done so. And your readers will be able to tell.
