"As Granny Weatherwax once said, if you wanted to walk around with the head in the air, then you needed to have both feet on the ground. Scrubbing floors, cutting wood, washing clothes, making cheese – these things grounded you, taught you what was real. You could set a small part of your mind to them, giving your thoughts time to line up and settle down."
