Just read this: "Every year, seemingly due to New Years' resolutions, sales of cigarettes drop by about 30 percent in January, but then regain half that in February, and are back to normal levels in March."
I say the same applies to gym memberships, diets, and any other "behavioral change" tied to a date. No need to tie life improvements to milestone dates like New Years (or Lent, etc). I postulate that enduring change doesn't occur overnight and doesn't care about the date -- so start now, keep at it, don't give up.
PS. The same applies to the other 1-day celebratory events: Valentines Day, Birthday, Mother's / Father's Day and even Christmas. Celebrate the moment and the person (as applicable) every day, space it out. It's less expensive than 1-time, all-out blowouts and - more importantly - the person (or persons) will appreciate the longer-term commitment. Space out the love and fellowship throughout the whole year!
What is the difference between being comfortable versus being complacent? I have no idea, so I challenge myself. Challenge my thinking, my parenting, my husband-ing; attempt to challenge my assumptions and my understanding of things. I won't get it right all the time so I welcome all constructive feedback. The goal? To "...be satisfied with life always but never with one's self." (George Jean Nathan)
