Where others have gadgets and tutorials to help them get better with design, I have books. The Elements of Style has a permanent place among the few books I have on my desk. In more occasions than I can remember, I have found in it my very own personal guide in design.
Do not explain too much.
It is seldom advisable to tell all. Be sparing, for instance, in the use of adverbs after “he said”, “she replied” and the like: “he said consolingly”; “she replied grumblingly.” Let the conversation itself disclose the speaker’s manner or condition. Dialogue heavily weighted is cluttery and annoying. Inexperienced writers not only overwork their adverbs but load their attributes with explanatory verbs: “he consoled,” “she congratulated”. They do this, apparently in the belief that the word said is always in need of support, or because they have been told to do so by experts in the art of bad writing.

The same goes for design. Don’t tell all. Keep something back. Let the design speaks for itself without the need to anticipate interpretations. And don’t do things because you have been told to do so by the experts in the art of bad design.
Good design does not need a supporting story.
