Girls are showing up, shaping popular culture for the better. Their choices tell us about friendship, connection, and how to forge joy in this world.

Of course, the power of girls as consumers and taste-makers isn’t new. And life remains pretty damn hard for young people. But when I see the Swifties in their ecstatic thrall, or the pink-clad Barbie hordes stampeding toward the theater, I think: We could all use a little more of that sincerity and exuberance in our lives.
