Actually, the first day of a whole Mitford week:
“Just writing to keep in touch, aren’t I, and because for the moment I’m a touch stuck with the book. Also to let you know I’ve started on a tremendous program of self-improvement. It consists of: 1. Getting up at 7 or earlier each day. 2. Doing the stomach and waist exercises (Reduce in Record Time) 15 minutes morn and eve. 3. A diet, 600 to 800 calories INCLUDING LIQUOR. 4. Doing my book first thing till at least lunch time.”
