How about just setting a goal of five pounds? Once you've hit that goal, set another small one. Sometimes having a specific date in my when setting the goal helps, like maybe by Labor Day. I don't know how much you have to lose, but say it's 60 pounds, that seems like so far away, so set it for 5 and then reward yourself when you hit that one. It's kind of like the AA slogan, one day at a time, just make this one pound at a time.
Good luck,
Judy
