Nearly four years ago, we published Sophia Dembling’s Confessions of an Introverted Traveler on World Hum. The essay was a huge hit: It generated more than 100 comments and became our most-read story of the year. (A follow-up piece, Six Tips for Introverted Travelers, landed second on the most-read list.) It also launched what Dembling calls “the beginning of my career as a professional introvert.” She went on to blog about introversion for Psychology Today, and in December, Perigee published her book on the subject: The Introvert’s Way: Living a Quiet Life in a Noisy World.

As a fellow introvert, I couldn’t be more (quietly) thrilled.
