Hugh van Cuylenburg was a primary school teacher volunteering in northern India when he had a life-changing realisation: despite the underprivileged community the children were from, they were remarkably positive. By contrast, back in Australia, Hugh knew that all too many children struggled with depression, social anxieties and mental illness. His own little sister had been ravaged by anorexia nervosa. How was it that young people he knew at home, who had food, shelter, friends and a loving family, struggled with their mental health, while these kids seemed so contented and resilient? He set about finding the answer and in time came to recognise the key traits and behaviours these children possessed were gratitude, empathy and mindfulness.
