I've always found New Year's resolutions a little funny. Why wait till the year end to set a goal. Set the goal when it comes to you. I have set and started New Year's resolutions on December 26th, January 8th and any other date you can think of.
We are such suckers for round numbers and new dates.
ya waiting until the end of the year and setting a goal you've already achieved sounds sensible to me
happy new year
