“It becomes the standard greeting everywhere: I am so busy. We say this to one another with no small degree of pride, as if our exhaustion were a trophy, our ability to withstand stress a mark of real character. The busier we are, the more important we seem to ourselves and we imagine, to others. To be unavailable to our friends and family, to be unable to find time for the sunset (or even to know that the sun has set at all), to whiz through our obligations without time for a single, mindful breath, this has become the model of a successful life.”
