“Discomforts are only discomforting when they’re an unexpected inconvenience, an unusual annoyance, an unplanned-for irritant. Discomforts are only discomforting when we aren’t used to them. But when we deal with the same discomforts every day, they become expected and part of the routine, and we are no longer afflicted with them the way we were. We forget to think about them like the daily disturbances of going to the bathroom, or brushing our teeth, or listening to noisy street traffic. Give your body the chance to harden, your blood to thicken, and your skin to toughen, and you’ll find that the human body carries with it a weightless wardrobe. When we’re hardy in mind and body, we can select from an array of outfits to comfortably bear most any climate.”
