Bittersweetness recognises that light and dark, birth and death—bitter and sweet—are forever paired. As Bittersweet shows, our obsession with happiness is not making us happy, healthy or whole. It's only by embracing our darker emotions—as well as the light—that we discover our deepest meaning and connection, love and joy. It can change the way we work, the way we create and the way we love—for it is the hidden source of our love stories, moonshots and masterpieces.

Intelligence is usually seen as the ability to think and learn, but in a rapidly changing world, there's another set of cognitive skills that might matter more: the ability to rethink and unlearn. In recent months, the pandemic has forced us all to reevaluate our assumptions about health and safety and multiple acts of police brutality have challenged most of us to reconsider our responsibility for fighting racism. Yet in our daily lives, too many of us still favor the comfort of conviction over the discomfort of doubt.
