Why does everyone study children, babies, and teens but not really 20 something-year-olds? After all, we’re still in development, and a lot of shit is still an enigma. Luckily, there is one psychologist that can help us out.

Meet Meg Jay, a Clinical Psychologist, and an Associate Professor of Human Development at the University of Virginia, who specializes in adult development and in, you guessed it, twentysomethings. Her books have been translated into more than a dozen languages and her work has appeared in the New York Times, Wall Street Journal, Harvard Business Review, NPR, and BBC. Her TED talk “Why 30 Is Not the New 20” is among the most-watched of all time.
