The following verbatim paragraph comes from William Zinsser’s On Writing Well:
For writers and other creative artists, knowing what not to do is a major component of taste. Two jazz pianists may be equally proficient. The one with taste will put every note to work in telling his or her story; the one without taste will drench us in ripples and other unnecessary ornaments. Painters with taste will trust their eye to tell them what needs to be on the canvas and what doesn’t; a painter without taste will give us a landscape that’s too pretty, or too cluttered, or too gaudy—anyway, too something. A graphic designer with taste knows that less is more: that design is the servant of the written word. A designer without taste will smother the writing in background tints and swirls and decorative frills.
