I have the perfect body (for me)

My body was not perfect; and I did not let myself forget it. In fact, I had a pretty incredible body. I wasn’t horribly critical, but nor was I content. I still thought I needed to lose another 5 to 10 pounds. What is it about us and the “last 5-10 pounds?” Is it even possible to lose those last 10 pounds? I mean, once we lose it, are we happy, or do we then say “oh, if I could just lose another 5 pounds THEN I’ll be happy”?
