In this episode I am joined by Dr Helena Marujo, who describes herself as a joyful, socially engaged citizen and an activist through science. I love that.

Helena traces the moment she realised she wanted to move beyond only measuring depression in young people and start asking different questions - ones about hope, justice, love and community. From there, her work has flowed into neighbourhoods, schools, ministries and global peace projects.

What stayed with me most was her belief that our small “handfuls of sand” - a letter to neighbours, a conversation in a local salon, a community gathering - genuinely change the larger desert we share. If you have ever wondered whether what you do in your own street, family or team really matters, this conversation may give you heart.
