Several other good authors are quoted within the book. Zinsser admires these writers for varying reasons, but they all write well. They all bring their unique personalities into the writing and have highly developed skills with the language. Some of this is talent, but Zinsser emphasizes that writing is a learned skill, a craft like any other. Good writers get that way from constant practice, through an admiration of the English language, and by way of an obsession with perfection.
