My first one was to lose weight. After reaching a high of 198 pounds last spring, I thought enough was enough and made it to around 163 by the end of the year. I don't want to exceed 170, and as long as I keep myself disciplined, I don't think I should have trouble keeping to this goal.
My second one was to take a walk outside for at least an hour every day. This one I had to break immediately, as the temperature in my city is currently about -18° celsius and there have been emergency cold warnings all week. I walked about 500m today, for about 5 minutes, and even then I felt the chill.
