Why wait until New Year's? We all know things that we can do better to improve our health. Why don't we do them? Are we afraid to fail or look funny? I can tell you that the results are worth the effort and the possible embarrassment. Get started. One step at a time, one workout at a time. One meal at a time.
Write down goals and keep track of speeds, inches, number of days that you exercise--something that will help you see progress. Give yourself rewards--gold stars, new clothes, shoes, or workout DVD. Race yourself. Compare yourself to yourself.
Starting new things is hard, but we can all do hard things. Put yourself on your "to do" list. Changes take time, they don't happen overnight. Being consistent is the key.
