Breaking bad habits often feels like a test of willpower. We tell ourselves we’ll stop scrolling, eat better, or exercise more — and then fall right back into the same routines. So why is lasting change so hard?

As part of our spring cleaning series, we’re revisiting a powerful episode from The Happiness Lab archives that reveals a surprising truth about behavior change: it’s not about willpower at all. Dr. Laurie Santos sits down with psychologist Wendy Wood to explore what the science of habits really says about why we get stuck — and how we can finally change.

Along the way, we hear the remarkable story of American soldiers in Vietnam who abruptly overcame heroin addiction after returning home, offering a powerful clue about how habits really work. If you’re looking to break a bad habit or build a better one, this episode shows how small changes to your environment can make lasting change feel almost automatic.

Forgiveness might sound simple, but it's hard to let go of the anger that comes with being deeply hurt. Grudges, bitterness, and frustration with life’s unfairness can quietly build up over time and take a real toll on our mental and physical health.

As The Happiness Lab kicks off a new season on spring cleaning your wellbeing, Dr. Laurie sits down with psychologist Dr. Fred Luskin, director of the Stanford University Forgiveness Project, to explore what research says about forgiveness. Why is letting go of resentment so much harder than it sounds? And what does it really mean to forgive someone?

Plus, we revisit a powerful story from the archives that shows what forgiveness can look like in the face of profound loss and why it might be the most radical act of self-care we can take.

Why is social media so hard to quit? We waste hours scrolling, feel worse when we log off, and still find ourselves going back for more.

Dr. Laurie sits down with Dr. Cass Sunstein, co-author of (00:00:57) Nudge, to explore a new concept from the 2026 World Happiness Report: the “product trap.” Together, they unpack why we keep returning to platforms that make us unhappy — and what it might take to finally break free.
