“Jealousy baffles me. It’s so mysterious and it’s so pervasive. … And yet I’ve never read a study that can parse to me its loneliness, or its longevity, or its grim thrill.

In fact, I don’t know that it’s an exaggeration to say that if we didn’t have jealousy, we wouldn’t even have literature.” New York Times Book Review editor Parul Sehgal takes listeners to church in her TED Talk, “Ode to Envy.”
