“I don’t know why we take our worse moods so much more seriously than our best, crediting depression with more clarity than euphoria. We dismiss peak moments and passionate love affairs as an ephemeral chemical buzz, just endorphins or hormones, but accept those 3am bouts of despair as unsentimental insights into the truth about our lives. It’s easy now to dismiss (it) as nothing more than the same sort of shaky, hysterical high you’d feel after getting clipped by a taxi. But you could also try to think of it as a glimpse of reality, being jolted out of a lifelong stupor. It’s like the revelation I had the first time I ever flew in an airplane as a kid: when you break through the cloud cover you realize that above the passing squalls and doldrums there is a realm of eternal sunlight, so keen and brilliant you have to squint against it, a vision to hold on to when you descend once again beneath the clouds, under the oppressive, petty jurisdiction of the local weather.”
