If you're not also reviewing your past year and learning the lessons. New year's resolutions are such a cliche that the "resolution-try-fail" cycle is almost a given. Focus instead on where you've learned or grown (intentionally or not) this past year and how you can apply that experience going forward.
"Boast not thyself of tomorrow, for thou knowest not what a day may bring forth." - Prov. 27:1
