The second habit is exercise. Make a goal of going outside for a walk every day. Studies have shown that when you connect with nature, you are less depressed, especially during the winter months. I have made a habit of walking outside every day in sunshine, rain or snow, although my neighbors probably think I am crazy for venturing out on blustery winter days. If you need accountability, ask a family member or friend to meet you for a walk. If walks are not your thing, find something else that gets you moving on a regular basis and make it a part of your day.
