Hugh van Cuylenburg spent a few months living and volunteering in India in 2008. Despite the fact that the villagers didn't have very much the were very happy. When Hugh got back to Australia he continued his studies and worked out that the key to the villager's happiness was gratitude, empathy and mindfulness. He wrote a book called The Resilience Project and now there is an app. It is only $4.49 and is available on android and iTunes. You can find out more about it in the video below.
