" Those of you who have managed to avoid vacuuming don’t know what you’re missing: an onerous chore, yes, but also a fine opportunity—no less taxing than balancing your books or getting the footnotes straight on your dissertation or working out a kink in your golf swing—for practicing some of the skills you’ll need on the path. The person who can vacuum an entire house without once losing his or her composure, staying balanced, centered, and focused on the process rather than pressing impatiently for completion, is a person who knows something about mastery.
