I really like that "SMART" guideline. It helped me to formulate my list. I paid attention to specific and measurable on all of them, but with I also realized that realistic and attainable SHOULD change over time, so I built some of that in. Here is my list:
Exercise
min 15 min per day, 4 days per week (increasing to 20 min/5 days, 25/6, 30/6 in Feb, Mar, Apr)
Food
* count carbs, adjusting daily maximum as necessary each week, starting with 25 (with the final goal to be somewhere between 50 and 100, depending on where I find my "sweet spot" for weight loss and not feeling deprived)
General Weight Loss
* accurately track exercise, carb count, and weight to see when adjustments need to be made
I also used this list to help me set some goals for keeping my house in better shape and being a better mom.
