Mine have been the same for a few years now.  Each year I merely reaffirm of the vows I've made since, for the most part, I've been following them pretty closely.  Here they are in no particular order:

JOG (I do this 3-4 times per week. no marathons; I only do about 2.5 miles each time.  I also ride my bike to work.)

READ (not just books, but I also try to keep up with Harper's and National Geographic)

CHEW (this is, surprisingly, the hardest to remember--following the old addage "20 times on each side" is very difficult to live up to).

I guess they're all sort of inner maintenance rules to keep me going for many New Year's Days to come.
