In the final chapter of The Elements of Style (Allyn & Bacon, 1999), White presented 21 "suggestions and cautionary hints" to help writers develop an effective style. He prefaced those hints with this warning:
Young writers often suppose that style is a garnish for the meat of prose, a sauce by which a dull dish is made palatable. Style has no such separate entity; is nondetachable, unfilterable. The beginner should approach style warily, realizing that it is himself he is approaching, no other; and he should begin by turning resolutely away from all devices that are popularly believed to indicate style—all mannerisms, tricks, adornments. The approach to style is by way of plainness, simplicity, orderliness, sincerity.
Writing is, for most, laborious and slow. The mind travels faster than the pen; consequently, writing becomes a question of learning to make occasional wing shots, bringing down the bird of thought as it flashes by. A writer is a gunner, sometimes waiting in his blind for something to come in, sometimes roaming the countryside hoping to scare something up. Like other gunners, he must cultivate patience; he may have to work many covers to bring down one partridge.
You'll notice that while advocating a plain and simple style, White conveyed his thoughts through artful metaphors.
