Making resolutions is about setting reachable, attainable goals. Are you going to lose weight? Define how much. Are you going to give up something? Define what that thing and exactly how you plan to avoid it. All that said, setting goals to improve ourselves on the outside will never heal what's on the inside. Just like a book cannot be judged by its cover, a person's health can't be judged by their body fat percentage.
When I was obtaining my degree in Exercise and Sport Science from OSU, I learned that all SIX components of our well-being are glued together. We are more than just physical creatures, and a holistic approach looks at our emotional, spiritual, environmental, social, and mental states as well. When one shifts out of place, it affects the other categories. For example, I don't feel like being out in public socializing when I feel fat because I haven't worked out in ages!
My challenge to myself every year is to set goals for my whole being. So don't just focus on specific goals for your physical self; set some reachable goals for your social, spiritual and environmental self too! Then, when 2013 rolls around, you'll be in the best OVERALL shape of your entire life!
