One of my all time favorite movie lines is from Forrest Gump. Forrest gets word from "some kinda fruit company" that they don't have to worry about money no more. His response is "That's good. One less thing."
I love the wisdom of this simple line. People laugh because the commonly held view is that not having to worry about money any more would solve many other worries as well. But, I say that getting rid of even a major worry, like money, really is just one less thing. The same holds true for weight loss. Losing weight is not going to magically make life perfect. It doesn't fix life's other problems. Now, don't get me wrong, losing weight is a wonderful thing. It can fix some medical problems, and definitely improves quality of life all around. But, it's not going to make you like your hair, or your job, or yourself. Don't wait until you are the ideal size to start living your life. Learning to be happy with yourself and your life actually makes it easier to lose weight.
