There are a lot of ways to stay motivated. When I first got started, I loved looking at the goal stories and pictures on the goal forum. Seeing how much those women have lost really helped me to keep going. I also found motivation by telling my husband, mother, and best friend about my goals. I text them every weigh-in (every Friday morning) with how much I've lost and what my current weight is. That keeps me motivated because I don't want to report a gain to them.
I've been working at this since the beginning of July, hardcore since the end of July. Now that I'm in the thick of it, I can find motivation within myself. All I have to do is look in the mirror, see how much more tone and defined my body looks, and that's it! I'm off to the gym! Or I think of how exciting it is to see a 2 pound loss on the scale, and it's easy for me to avoid high calorie meals.
It gets easier as you go, but at the beginning, 3FC definitely helped me. Just reading everyone's daily struggles - and being able to relate to them - helped me a lot.
Good luck to you!
