Have you gotten a new look to go with the weight loss? Show off that new figure! Try a new style just because you can. What about a new haircut? Several of my DB friends got sassy shoes and we compared notes on those.
Then take your new hot looking self out and turn some heads. It's a great way to jump start rebuilding your self esteem.
If you love somebody, set them free. http://tinyurl.com/2empx2g
