Here's my recommendation on this whole "new you" topic: Spread some goodness in the world all year long instead of focusing on weight, success, smoking, etc. In case you haven't already figured it out, the universe does not revolve around your personal wants, needs, and/or fitness goals. Everyone has a personal "fix" they need to address, unless you're Angelina Jolie or George Clooney, of course. Instead, why not make the new year about being a better person to others?
Pay it forward. Give a compliment. Say a prayer for someone. Expect less. Be nice. Open a door. Offer up your seat. Tip generously. Say "thank you" and "you're welcome." The list goes on and on.
I'm thinking a ginormous amount of happiness could result - as opposed to the inevitable breaking of a resolution too unattainable to keep. Alert the media? Let me know how you do on this.
