Sure! Here's a few things that have helped me (please don't be offended that I posted this in a few places on the site, it really is what's helped me)
*Set goals--lots of them. Monthly goal, Mid-way goal, Ultimate goal, calorie goals, exercise goals, etc...
*Join some challenges here at the forum---it's always easier to get motivated when others are going along with you.
*Do not kill yourself over a 'bad day'. It's going to happen, so just let it be and try harder the next day.
*I know some people buy an outfit in their goal size and hang it out so that they see it every day. I personally buy new clothes (not a whole new wardrobe, just some new items so that I'm not swimming in all my old fat clothes) when I go down a size or two. It's lots of fun!
*The more time I spend here, the more motivated I am. There's something about seeing other people dropping the weight that makes me feel more comfortable.
