Chris Caterine earned his PhD and spent the first years of his career as a professor of classics before leaving the professoriate to work as a corporate proposal writer and communications strategist. Since then, he has spent his evenings advising others on how to change careers — and recently published “Leaving Academia: A Practical Guide” with Princeton University Press. In this interview, Chris will discuss his book, the emotional challenges of giving up on a vocation, and strategies to help you figure out who you’ll be if you cease to be an academic.
