In this Huberman Lab Essentials episode, I explain how to create lasting habits and break unwanted ones. I explain two habit-building systems: one aligned with daily rhythms and another based on a 21-day cycle of forming and reinforcing habits. I also discuss why habit formation differs between individuals and how certain "linchpin" habits can make other behaviors easier to adopt. Finally, I share practical tools—including visualization, task bracketing, and methods for rewiring bad habits—to support lasting behavioral change. Read the episode show notes at hubermanlab.com.
