Why is it so hard to break bad habits and replace them with good ones? You may think it all comes down to willpower. But social psychologist Wendy Wood says that if you really want to change your life, you need to tap into your unconscious mind. She would know. Wendy is the world’s foremost expert on habits and the author of “Good Habits, Bad Habits: The Science of Making Positive Changes That Stick.” Today, she chats with Next Big Idea Club curator Adam Grant about harnessing the science of habit formation to improve your life for the better. This conversation was among the first that we aired on this podcast, and we left a lot of great moments on the cutting room floor. Today, we’re restoring them. What follows is an extended version of Wendy and Adam’s conversation with new insights about overcoming chronic lateness, developing sustainable exercise routines, and making New Year’s resolutions that last past February.

The science is clear: people who engage in spiritual practices live longer, happier, healthier lives. For the past few years, two researchers — Dave DeSteno, who runs the Social Emotions Lab at Northeastern, and Lisa Miller, founder of the Spirituality Mind Body Institute at Columbia — have been trying to figure out why. They’ve found that treating religious rituals as tools we can adapt to our individual needs and values can help all of us — staunch atheists and devout believers alike — live more meaningful, successful, and connected lives. In this episode, Dave and Lisa share what they’ve learned, discuss the fraught relationship between science and organized religion, and offer tips for making the most of your holiday rituals.

What if everything we think we know about the history of our species is wrong? That’s the provocative question at the heart of a new book by today’s guest, David Wengrow. Hailed as fascinating, brilliant, and potentially revolutionary, “The Dawn of Everything: A New History of Humanity” debuted at no. 2 on the New York Times bestseller list. Drawing on the latest research in archeology and anthropology, it suggests that the lives of our ancient ancestors were not nasty, brutish, and short. On the contrary, they were playful, collaborative, and improvisational—and there's a lot they can teach us about how to improve the world as we know it.

In “Dopamine Nation: Finding Balance in the Age of Indulgence,” Dr. Anna Lembke says today’s superabundance of pleasurable stimuli makes us all vulnerable to overindulgence. But don’t lose hope. Anna, the medical director of addiction medicine at Stanford, says that by understanding how modern stimulants — from Instagram to masturbation machines — prey on our primitive brains, we can find ways to overcome the unhealthy dependencies that prevent us from leading balanced lives.

From the time she was in high school, Shellye Archambeau had one dream: she wanted to run a business. Ultimately, she pulled it off, becoming one of Silicon Valley’s first Black female CEOs. But getting there was far from easy. She had to learn how to assemble a network of mentors, overcome imposter syndrome, and challenge herself in ways she could never have imagined. The story of how she did it is the subject of her inspiring book “Unapologetically Ambitious: Take Risks, Break Barriers, and Create Success on Your Own Terms,” which was named one of the best of the year by our Next Big Idea Club curators. Today, one of those curators, Susan Cain, chats with Shellye about developing resilience, overcoming adversity, cutting yourself a break when it comes to work-life balance, and pursuing your ambition even if you’re an introvert.

We’ve all seen the meme. Two images, side by side. On the left, a photo of Jeff Bezos circa 1998. His hair is receding, his smile geeky, his sweater bulky and brown. The caption? “I sell books.” Then, on the right, there’s Jeff in 2017. His pate is as smooth as Lex Luther’s, his biceps as bulbous as Vin Diesel’s, a satisfied look on his sunglassed face. "I sell whatever the f**k I want,“ reads the caption.

That meme is a pretty good metaphor for the era of radical change through which we are living, an era Azeem Azhar calls "the exponential age." Breakneck advances in technology allowed a humble bookseller to become chieftain of the world’s largest online retailer. And don’t expect those technological advances to slow down anytime soon. In the next few decades, new developments in everything from AI and 3D printing to synthetic biology and gene-editing won’t just change the way we live: they’ll allow already monolithic companies to keep growing at an unprecedented pace while our elected leaders scramble to keep up.

The gap between rapidly advancing technology and our slow-moving society is the subject of Azeem’s marvelous new book, “The Exponential Age: How Accelerating Technology is Transforming Business, Politics and Society.” Recently named one of the best books of the year by the Financial Times, it’s at once a rousing survey of the new technologies that may change the way we live and, at the same time, a pointed reminder that those transformations will have profound political, economic, and social consequences.

Colleges, businesses, and bureaucracies have long operated on an "old power" model — rigid hierarchies that rule from the top down. But Henry Timms says that paradigm is going extinct. In his book, "New Power: How Power Works in Our Hyperconnected World — and How to Make It Work for You," Timms argues there's another force emerging. It's transparent, collaborative — and it's going to embolden all of us to change the world from the bottom up.
