Every season, we invite the authors of the best new non-fiction to distill their books into five big ideas. Then they read those ideas aloud. We call these book bites, and our app has hundreds of them. In this special episode, we’re sharing three book bites that demystify the art and science of parenting. Journalist Melinda Wenner Moyer offers evidence-based strategies for teaching your kids not to be jerks. Two educators explore the science behind the iconic TV show “Mr. Rogers’ Neighborhood.” And acclaimed economist Emily Oster explains how geeking out on data can make you a better parent.

Conventional wisdom tells us that real joy comes from within: from exercise or meditation, acts of service or the way we look at the world — pretty much anything except material possessions. But author/designer Ingrid Fetell Lee offers a different take in her book “Joyful: The Surprising Power of Ordinary Things to Create Extraordinary Happiness.” Last season, Ingrid sat down with Next Big Idea Club curator Adam Grant to discuss the powerful relationship between the way we feel and the objects that surround us. Turns out we can harness that relationship to live healthier, happier lives. If you haven’t heard this episode before, you’re in for a treat. And if you have heard it before, there’s never a bad time to be reminded that joy is all around if you know where to look.
