I have my slim mirror and my fat mirror, one in the bathroom is always flattering and the one in the bedroom is not as kind, so when i feel I look good in that one I know I have will have the results I want.
When I went to the Weight Watcher meetings they had a "magic mirror" It was one of those mirrors that makes you look thinner. I think it made you look something like 20 lbs thinner. I remember the first time I looked into it and I never thought I could actually look like that. But now I don't need the "magic mirror" anymore, it's a good feeling.
