As a young child, Tania Luna left her home in post-Chernobyl, Ukraine, to take asylum in the US. And one day, on the floor of the New York homeless shelter where she and her family lived, she found a penny. She has never again felt so rich. A meditation on the bittersweet joys of childhood -- and how to hold them in mind. Tania Luna specialises in organisational psychology, emotion regulation, and surprise psychology. She is a leadership trainer, researcher, writer for various publications (including HBR and Psychology Today), and co-author of the book Surprise: Embrace the Unpredictable & Engineer the Unexpected.
