Ah, I was looking forward to this thread.  
Last year's resolutions were to a) simplify, b) diet & exercise, and c) do more RPG one-shots.  A & B should continue; C is a non-issue for now.  
This year's...
A) Diet & Exercise.  I lost 15 or so lbs last spring/summer, but it's creeping back on.  I need to keep doing a good job of journaling my food, and getting some exercise in most days of the week.  When the weather is good, the best exercise is a vigorous walk.  When it's bad, I have weights, my bike on a trainer, and aerobics videos to use.  There's no reason I can't at least hold the line on my weight until spring rolls around and I can amp up my exercise level a bit.  
B) Keep Winter from Defeating Me:  as I've said many times in the past, the winter blahs can bring depression and physical sluggishness into my life.  I should find interesting things to do to keep me stimulated until March rolls around.  
C)  Try to Find Where RPGs Fit Into My Life.  I miss playing but not enough to go back to running a regular game.  
D)  Health-Related.  Diet & excercise are vital to good health but I have some other stuff I need to attend to in this area (make various appointments).
