"I get so impatient at times that I have to go off by myself and read St. Francis de Sales' letters to calm myself." Dorothy Day, Diaries.
Great idea. I don't have his letters, but I do have Pauline Books' nifty Courage in Chaos, Wisdom from Francis de Sales. Given my dearth of patience, I may have to start carrying it around in my back pocket.
And maybe I should tattoo this passage from her Diaries on my forearm: "In reality it takes heroic virtue to practice patience in little things."
