Writing before dawn began as a necessity—I had small children when I first began to write and I needed to use the time before they said, “Mama”—and that was always around five in the morning. Many years later, after I stopped working at Random House, I just stayed at home for a couple of years. I discovered things about myself I had never thought about before.

I love swimming and I'll still be found in the pool, but now I'll be able to do without the 04:30 alarm!

You know, down the hall and up the stairs from this office is the part of the White House where the President and his family live. There are a few favorite windows I have up there that I like to stand and look out of early in the morning. The view is over the grounds here to the Washington Monument, and then the Mall and the Jefferson Memorial. But on mornings when the humidity is low, you can see past the Jefferson to the river, the Potomac, and the Virginia shore. Someone said that's the view Lincoln had when he saw the smoke rising from the Battle of Bull Run. I see more prosaic things: the grass on the banks, the morning traffic as people make their way to work, now and then a sailboat on the river.

Our life here is simple, very simple. Get up in the morning, go for a run, come back. If it is a day for cleaning, we do the cleaning, or we just relax. Then go for lunch, massage, the 4 o'clock run, evening tea, relax, go to sleep. As simple as that.

You know that sickening feeling of inadequacy and over-exposure you feel when you look upon your own empurpled prose? Relax into the awareness that this ghastly sensation will never, ever leave you, no matter how successful and publicly lauded you become. It is intrinsic to the real business of writing and should be cherished.

Always carry a notebook. And I mean always. The short-term memory only retains information for three minutes; unless it is committed to paper you can lose an idea for ever.
