Today I woke early and blew my hair dry. Soon I will put on work clothes, drive to Metro, ride the Orange Line to Metro Center, switch to the Red Line, walk from Judiciary Square to the Law Center -- and return to routine. For 17 years I worked out of our house. Whole weeks would go by when I would only wear slippers. Last week's snow holiday was a brief return to that world. It was nice; I won't deny it. But there is something about getting up and getting out of the house that is good for creativity. So even though I long to spend today with my books and my laptop, a walk through the woods and a cup of tea after I come back inside, I will instead shoulder my bag and head out into the world.
