I'm Nicolas. What Matters is a place for conversations about the subjects that shape our everyday lives.
I was born in France and hold a master's degree in philosophy — a training that still shapes the way I ask questions today.
From the challenges we face in relationships to sleep, mental health, the way we think and the way we live, I want to explore the full range of what it means to be human.
I sit down with people who have spent years studying, working with or living through these questions, and follow the conversation wherever it leads.


What Matters started from a simple idea:
Some conversations are worth taking the time to have.
Each conversation starts with a question worth asking. Together, we look closely at the ideas, experiences and research that can help us understand ourselves and each other better.
