For me I learned years ago not to have a new years resolution, it only set me up for failure. Instead I set mini goals of no more than 1 or 2 months out. That way I can use the "SMART" statement:
S Specific about what is to be accomplished.
M Measurable in terms of how do you know if the goal has been achieved.
A Attainable in terms that the goal is both realistic and achievable.
R Results oriented or targeted to achieve a clear outcome.
T Time line is set and steps to goal attainment are clear
So right now I am doing the ww challenge and set a goal of losing 10lb by the end of the 10 or is it 12 weeks can't remember now
I use this a lot in other areas of my life too seems to keep me on track just like my food journal
