Someone on here once posted that instead of setting weight-related goals, she set behavior-related goals. Instead of saying, "I'm going to lose x pounds," she said, "I'm going to stay on plan for 30 days." Often we get frustrated staying on plan BECAUSE we are not seeing pounds or inches disappear. How about plan for the sake of plan (this is basically what Kaplods said, but framed a little differently)?
Exercise goals can be the same. How about, "I'm going to do the Couch-to-5k program?" For me, setting and achieving an exercise goal is particularly fulfilling -- and I have complete control over it. I decide every day to get my butt out the door. If you do each training session as assigned, you WILL be able to complete a 5K at the end (barring health issues). It is EMPOWERING!
I agree about being obsessed -- my husband kind of smirks when he catches me weighing 5 cherries (or recording 2 slices of peach pie
) -- but before I was obsessed with counting calories (and 3FC) I was obsessed with pinching fat parts of my body, or sucking in my stomach, or whether or not I could wear leggings, or what dress would fit for that holiday party? When I am overweight, I am obsessed with my weight and the unhappiness it brings. At least now my obsession makes me happier and healthier. 
Last but not least,
