I was reading someone's blog on Xanga, and she had created a model of herself on the following website... one of her weight, height, etc. now... and the other of where she hopes to be. I did the same and found it very motivating to keep going!!!
You can even rotate the model to see side views, etc.
So anyhow, I thought I'd share the link in case any of you want to try it (you can actually goof around with the model without registering, and if you want to save 'em to your computer but not register, just right-click on the photo and choose "save as" and the location):

I was really surprised that the LARGEST different was when I modified my weight now by -15 lbs.
Gonna go exercise now...
