How are you doing with your 2013 New Year's Resolutions?
According to this article from a few years back, you've probably already broken them. If not, you'll probably only last a few more weeks at the most.

Try taking things one day at a time and set a smaller goal for yourself that will help you progress toward your ultimate goal.
