Every week in Wales, people stand up on stage and talk. They talk about their lives, their communities, their passions. Behind each talk is an idea. In this series, presenter Catrin Nye brings us some of the best of these - and then interviews the speakers to explore the central idea behind their stories, how their experiences have shaped them, and how they hope their talk will help to shape us.

In this episode, how possible is it to change ourselves and help others change their lives for the better? Catrin Nye presents three perspectives on how to make change.

The Idea is a Bengo Media production for BBC Radio Wales Show less
