Why is this time any different?

Someone on the boards asked all of the people who have done WW more than once "why did you leave WW last time"? I thought that was a fantastic question, and I thought for a long time about why I have lost and gained weight so many times in my life. Of course, it's a common phenomenon ("yo-yo dieting"). I've probably done WW 4 or 5 times seriously in the past, gotten to goal, and then gained all the weight back quickly (+10 extra pounds each time). I'm fantastic with the plan while I'm still losing weight, but once it's gone, I get over-confident and stop caring about what I eat.

So, I want to put down on 'paper' why this time is going to be different. Quite frankly, I'm tired of being obese. I like tying my shoes without being uncomfortable, dammit! Here's the action plan:
- Get down to 149 pounds (a relatively healthy BMI for me) using the regular WW plan
- Attempt to maintain for at least 6 weeks - figure out how many points my body can take without gaining (and try not to feel like a failure while doing so)
- Once I've successfully maintained for at least 4 weeks in a row, set a new goal (probably 139 pounds)

I'll also be thinking about this for the next little while to see if I can come up with more non-weight goals. If I have something to work towards, I think my job will be a lot easier!
