As the holiday season comes to an end, many of us may have indulged a bit in a lot of celebratory eating. As a freelancer, I think we run the danger of sitting in front of the computer screen way too much--this is, obviously, a hazard of our trade. Also, if you are working from home, you may be tempted to become lazy or complacent or to snack too much, etc. My question is how do you all maintain a healthy lifestyle as a freelancer in terms of body and mind? What routines work for you?
