Writing organizes and clarifies our thoughts. Writing is how we think our way into a subject and make it our own. Writing enables us to find out what we know-and what we don't know-about whatever we're trying to learn.
William ZinsserMy commodity as a writer, whatever I'm writing about, is me. And your commodity is you. Don't alter your voice to fit the subject. Develop one voice that readers will recognize when they hear it on the page, a voice that's enjoyable not only in its musical line but in its avoidance of sounds that would cheapen its tone: breeziness and condescension and clichรฉs.
