I'm not a loser

So I'm doing Weight Watchers at work. And I'm stubbornly staying at the same weight. My leader told me to try for just one pound. I'm just not inspired, man. And to top it off, my leader read off a list of names who had lost five, 10, 25 and even 50 pounds. I was seriously thrilled for them, but I can't seem to duplicate their success. Any tips?
