I don't know if you've already done this, but write down some small goals. Whether they be weight or otherwise and try to stick to them. I found that last year when I had the goal of losing a few pounds by vacation that I stuck with it, but then after vacation I faltered. So, now I'm back and have set some small goals for myself to keep a date in mind and keep my motivation up. Another goal I've made has to do with the DVD's I workout with. I am using the Insanity DVD's right now and want to be able to do more every week, so that keeps me motivated to work hard. A reward system is also motivating. Being able to buy some new clothes when you reach a goal, or a small kitchen appliance, take a trip, or whatever you want. You've obviously worked to lose the 19 lbs. that show here, so you can do this! Good luck!!
