Western psychology traditionally regards sorrow and longing as maladaptive at best, pathological at worst. We live in a culture that encourages us to telegraph how happy - or, on the flip side, outraged - we are. As a result, our collective empathy is spiraling downward, and we're ill-equipped to deal with our personal troubles. Yet a richer, truer existence is possible. The bittersweet way is the essence of creativity and a shortcut to love. From the bestselling author of "Quiet".
