A comprehensive and wide-ranging Vision Statement sets the stage for everything that follows in your weight loss efforts. This Vision Statement can (and should) provide both inspiration and direction.
Your Vision Statement should tell you why you want to lose weight or get fit, and why the hard work and effort to accomplish your goal is worth it. Your answers to these "why" questions can include some "general" elements (feeling good about yourself, being around for your grandkids, being a good role model, having the career or relationship you really want, etc), but as much as possible, the big picture you paint here should have specific details. You can generate this detail by asking yourself questions like:
Your Vision Statement should tell you what else (besides your weight) needs to change within yourself and your life to help you get from where you are now to where you want to be. For example, you could take the list of ranked values you created above and compare that to the values that appear to be guiding your life right now; you could compare your ideal day to your typical day now.
It is crucial NOT to get down on yourself over the way things are now. Make sure you are focusing on what you CAN do to change your life as you see fit. If you aren't ready to give up the self-blame, skip this part of your Vision Statement for now.
