“We all run on two clocks. One is the outside clock, which ticks away our decades and brings us ceaselessly to the dry season. The other is the inside clock, where you are your own timekeeper and determine your own chronology, your own internal weather and your own rate of living.

—Mary Barnett Gilson (1877–?)
“I’ve yet to meet a writer who could change water into wine, and we have a tendency to treat them like that.”
