Show Notes & Chapters

Most people have experienced the exhausting cycle of replaying the same thought over and over, convinced that it will eventually bring clarity. Usually, it doesn’t.

Dave and Luke dig into the neuroscience behind that cycle. They explain what rumination actually is, how it differs from healthy reflection, and why the brain so often defaults into looping when it has nothing else to do. From there, they move to strategy. A framework built on the three pillars of mental fitness (health and vitality, connection to others, and connection to self) for breaking out of the loop and regaining your freedom.
