Most of us gain weight as we age. My brother went from 185 to 313 over the course of ten years from giving up coffee to drinking soda.
He now pays himself a silver dollar every day he exercises for 30 minutes (which is about all he can do until he gets more weight off his feet).
Last summer he chose to buy a lawn mower that he pushes (instead of a ride-along). He has a nice big area to mow, so he uses the 30 minutes each day as a means to burn off more weight. He has made it his new life to figure out what else to do besides paying money to go to a gym.
I asked him how much he lost last month, and he said "five pounds". I asked him how he can get motivated to only lose five pounds in a whole month! His answer was, "David, that's 60 pounds a YEAR. It took me ten years to put this weight on, and I hope to knock it down with 60 pounds a year until I get back."
I guess he's right. I read how two celebrities both had heart attacks at young ages because they tried to lose too much weight too soon.
As for the pictures, you may want to keep your old clothes by your side as another motivator. I am amazed that most of the clothing sales are in the 30 to 34 inch waist, whereas my brother can never find a sale on his size. So more expensive clothes is another reason to get rid of the weight.
It's important for you to come up with a long list of reasons to keep at it.
I wish you the best,
