looking for motivation ti lose weight and not to fall of track

Honestly, besides knowing that I need to get healthy and increase self confidence, I plan something in the future that I know I need to lose for. Such as this morning I planned a trip to go to a convention and meet a few of my heroes. I have never been more motivated to get in shape. This is not to "look good" for them but to make sure I have the confidence I want to make the most out of the experience.
