The phrase "comparison is the thief of joy" might be the kind of cliché that makes you roll your eyes — and yet, it's an idea that is, scientifically, pretty accurate. In today's episode, psychologist Laurie Santos — a Yale professor and host of "The Happiness Lab" podcast — discusses some of the surprising evidence behind what does and doesn't make us humans happy. Laurie also shares strategies on how to improve our well-being, discusses the irony behind "self-care" and explains why happiness is often a journey not just within, but beyond, ourselves. This is an episode of How to Be a Better Human, another podcast from the TED Audio Collective. Listen to How to Be a Better Human wherever you get your podcasts.
