My last one was purpose. I wanted to concentrate my energies on doing things that serve a purpose for myself and others. I would say I did okay with it. I still wasted more time doing nothing worthwhile then I should have, but I figure everyone needs to have that kind of down time.
I haven't chosen one for next year yet, but I do have a few in mind. The top of the list is move. I am a pretty sedentary person who needs to move more for my health. But honestly, it sounds hard, so I may just go with something easier like eat. Eat is pretty easy for me. LOL Just kidding, kinda.
