I’ve concluded that bittersweetness is not, as we tend to think, just a momentary feeling or event. It’s also a quiet force, a way of being, a storied tradition—as dramatically overlooked as it is brimming with human potential. It’s an authentic and elevating response to the problem of being alive in a deeply flawed yet stubbornly beautiful world. Most of all, bittersweetness shows us how to respond to pain: by acknowledging it, and attempting to turn it into art, the way the musicians do, or healing, or innovation, or anything else that nourishes the soul.
