“ A voice is a product of the writer’s own Pandora Box of insight, insecurities, bravado, modesty, humility, affection, understanding, and confidence. In short, a voice reflects the writers’ sangfroid. The tenor of the writer’s voice also reflects their insecurities, self-doubt, egotism, testiness, and the ability to identify with their mental and physical infirmities. The inflection that distinguishes a writer’s pitch from other wordsmiths’ tone reflects their collective lifetime of mundane, tranquil, disturbing, and passionate experiences. ”
