2013 is knocking at our door, and across the world millions of people will vow to stop smoking, to sort out their budget, to start exercising, or to finally ditch junk food and eat more home-cooked meals.

If so, have you ever kept any of them for an entire year or beyond? Can you remember the ones you made a year ago? What are your resolutions for 2013?
