4:30 A.M. I never really sleep much and often start my day at this time. When I am very lucky and sleep through the night, I might get up at 7:00, but that is rare. The first thing I do when I get out of bed is weigh myself. I do this every morning, and if I have gained more than two or three pounds, I try to eat fruit and vegetables exclusively for a couple of days until my weight is back to my ideal. I make myself a tall glass of iced espresso (I don't like warm drinks), get into a hot bath, and slowly sip my drink as I come to life. Often I lie in the tub for a half hour and just let my mind wander. I find a bath meditative and usually prepare myself for the day in this manner. Once out of the tub, I throw on my gym clothes.

8:00 A.M. Typically, I answer my e-mails. On average, I get about 100 per day. Then I do a bit of work before working out with my trainer at 8:00. The home page on my computer is set to the Daily Beast Cheat Sheet, an excellent summary of the news of the day from different publications around the world. I work out at a gym at home with Pilates equipment, cardio equipment, and free weights. I usually do about 30 to 45 minutes of cardio and then a half hour of crunches, push-ups, stretching, and other exercises using my own body weight, as I can tend to bulk up quickly if I use weights more than occasionally.

9:15 A.M. After working out, I have a breakfast of whole-grain muesli or bran cereal, half a banana, and several slices of pineapple. Then I take another bath, this time with soap, and wash my hair. Naturally, I use my own beauty products; I wash my face with either my cream cleanser if my skin feels dry or gel cleanser if my skin feels particularly oily. I then trim my beard and brush my hair into place. I use my daily moisturizer and take my small makeup brushes to touch up any skin blemishes or dark circles with stick foundation (color no. 7). I put on my "uniform": a white shirt, a dark tie, a gold collar pin, a black or dark-gray single-breasted peaked-lapel suit, and black cap-toed shoes. I wear a variation of this look every day that I am in a city. (My other uniforms are for Santa Fe, Mustique, or a ski resort.)

I carry my computer and other work to the office in one of my black leather bags. Because I rarely walk in London, I never wear a coat. Actually, I tend to walk much more in New York. In L.A. and Santa Fe, I drive. I have a driver in London because I am slightly dyslexic and cannot drive in the U.K.; after all, the traffic runs the opposite way to that in the United States. An International Herald Tribune is always waiting for me; I find it the perfect newspaper for me, quite condensed with a quick global perspective on the news. Reading, or skimming, the paper usually takes me precisely the same time that it takes for me to get from my house to my office. I don't carry a phone with me because I hate talking on the phone and especially hate talking on cell phones. I do have an iPhone, but I use it primarily for music and as a camera. In an emergency, of course, I use it as a phone. I am not really even sure what my number is. I have an iPad but use it just for reading books or screenplays, and I carry my MacBook Air with me everywhere.

10:00 A.M. I usually arrive at the office by 10:00. I have a weakness for doughnuts and often completely ruin my diet by eating a doughnut or two when I arrive.

As president and CEO of the company, I spend a good bit of my day in business and design meetings. These might be women's ready-to-wear fittings, men's fittings, handbag-prototype reviews, footwear fittings, jewelry-design meetings, cosmetics meetings, or eyewear meetings. I tend to work on several different product categories on the same day. My executive team is scattered around the world, in London, New York, Los Angeles, Milan, Florence, Hong Kong, and Tokyo offices. Consequently, our meetings are often via Skype.

1:00 P.M. I hate going out for lunch during a workday because it slows down my pace and ruins my rhythm. I prefer to eat at my desk. Actually, I wander around the design studio with a plate in my hand as I dine on, for example, salmon sashimi and a salad of tomatoes and mozzarella. I often have a bit of dark chocolate after lunch.

6:00 P.M. Most nights, I work at the office until anytime between 6:00 and 8:00, depending on whether or not I have to go out to dinner. If I do have to go out at night, which I do about four nights a week, I try to take a 45-minute nap, have another hot bath, and put on a clean shirt.

8:00 P.M. I am not someone who likes cocktail parties or large dinner parties, but I have to attend them often. I much prefer very small dinners with close friends. I eat at the same restaurants in London most nights: Scott's, No. 35, J. Sheekey, Mark's Club, Harry's Bar, or Cut at 45 Park Lane. If I am meeting someone for drinks first, I always like to go to the Fumoir at Claridge's. My favorite evenings are actually spent at home. Richard [Buckley, Ford's partner of 25 years] is a great cook, and I love dinner in the kitchen with just the two of us and the dogs.

10:30 P.M. When we come home from a night out, Richard and I walk the dogs around Grosvenor Square and then head up to bed. Believe it or not, I usually take another hot bath and wash my face. Then we watch a bit of television (usually things we have recorded) or read and go to sleep. I don't wear anything in bed. In fact, I rarely wear clothes at all when I am at home.

MIDNIGHT I am usually in bed and with any luck will get a few hours of sleep!
