I remember a story one woman told me. She said that she used to watch a woman walk past her house every day, rain or shine, snow or wind, obviously for exercise, and thought to herself, "That poor woman! She is working so hard!" She only noticed peripherally that the woman was overweight.
Six months later, she looked out her window, and said to herself, "Who is that?" And it was with a sense of shock that she realized the woman walking past her house was the same woman who had been walking there every day...but was now unrecognizable and thin.
The point of the story is that it may be very hard work, and you may be embarrassed, but in about 6 months you will be a new woman!
