Ok, so this might be kind of weird since I'm showing 3 year old pictures here, but these pictures are one thing I'm using as motivation to show myself every day that I *can* do something about my weight.
In 2003, I reached my then-highest weight of 230 pounds. I joined a gym, I saw a personal trainer, I changed my eating habits. I was working nights at a tv station, and one of the things I did was to eat my dinner in two halves -- one around 5:30p and one around 8:00p. It seemed to help a lot personally with keeping me from wanting to go through the drive-thru on the way home at 10p. In about 3 months, I managed to lose 30 pounds. That year was also my year of too many weddings, so I had a few posed pictures from a wedding in March and a wedding in September that showed how well I had done. I was still lumpy and in the end about 200 pounds, but I still look at those pictures and I'm amazed at what I did for myself.
I don't have many posed pictures now, at 280 pounds. The full body ones that I could find aren't as nice as the old ones, and I'm not wearing make-up or any of that stuff. One is in a dress I bought off ebay for like $10 that I thought I might wear on my honeymoon if I could fit it and the other is from the day I bought my wedding dress, trying it on. The wedding dress does a GREAT job for how I feel about myself, but the pose is similar to the old 2 and you can see my giant arms. The other one is a little more true to my current shape. I yo-yo'd a lot over the summer, wound up losing about 10 pounds and then another 5 over the wedding/honeymoon week, but it all came back after I got home.
It's been a blessing to see so many progress pictures from other people, and my previous progress pictures help me a lot too. I know we've all struggled with our weight and I'm sure plenty of us have at least one picture from the past that reminds us that we can do something to help ourselves. If you have one of those, share it!
