William Strunk Jr. phrased it best in the must-have book for writers of all levels, Elements of Style:
“Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all his sentences short, or that he avoid all detail and treat his subjects only in outline, but that every word tell.”
There’s a tendency to fill writing with needless words; this can bog a reader down in details, distracting from your message. Mastering the art of decluttering words frees you to effectively capture readers’ attention, sparking intrigue and affirming expertise in what you are writing about.
