One of the things I find most relaxing when I am not working is going to a coffee shop or a bookstore cafe and sketching different sorts of people. I usually bring a black pen, a water brush, and my trusty Ipod. Especially at Starbucks, there is usually a steady stream of all kinds of people walking through. Some are leisurely, some in a hurry, some are either studying or deep in conversation. I also tend to bring a book and read for awhile if there's nothing to draw. This is a great way to exercise the drawing muscles, especially in these hectic computer days!
