Author of The Other Side of Happiness: Embracing a More Fearless Approach to Living
Professor at University of Melbourne’s School of Psychological Sciences

In today's world, feeling happy is no longer simply a state of mind. It's become a marker of mental health and success. On the flip side, pain and sadness are viewed as signals of failure and sickness. If we're not happy, then there is something wrong with us, and we need to fix it. It is no wonder that the painkiller and antidepressant markets, already worth billions of dollars, continue their rapid expansion. We've come to treat even commonplace experiences of pain and sadness as pathological, as things that need to be medicated and eradicated.
