Time for New Year's Resolutions again

Christmas has come and gone, it's now going to be the end of the year again. So as usual it's time again to look at New Year Resolutions again.

What do you think? Are New Year Resolutions necessary? Does it work? How many times have I made a new year resolution and end up not keeping it? Hahaha

So what do you Guys out there think ? Does it work ? Have you ever Kept to it? If you did how long did you keep to it for?
