Dr Mark Williamson explores how we can make life happier - for ourselves and others around us too. He shares the most exciting ideas from his many years' work as Director of Action for Happiness and his personal journey from 'stressed success-chaser' to a calmer and more purposeful life, including the actions he has found to have the biggest impact and how we can put these into practice.

This was filmed at an Action for Happiness event in London on 19 March 2019.
