Yeah, for someone who works from home, you'll often find me... not at home. ;)
Part of that is that I've got a way of making a living that doesn't require a lot of work every day, but part is just that I do my best thinking when I'm out skating, biking, or walking the dog. I throw on some music and work out a problem in my head, or I'll listen to podcasts or audiobooks that teach me something or motivate me to try new things.
Also, it's nice to get off the computer and out of the office frequently. :)
