The company I work for just revised it's vision, mission, and core values. I have been toying around with creating these for myself for awhile now to keep me on track. The problem with trying to get something in writing was that I wasn't clear on my target. On Weight Watchers I did set a target weight, but I am not really trying get to a certain weight. The goal I set was more to keep me on track to revamp my unhealthy lifestyle. I had to rethink my mindset to come up with a vision.
Vision - In 2-3 years I will be strong, fit, healthy, and energetic. I will enjoy an active lifestyle. I will be proud of myself. I will be a priority to myself.
Mission - I will embark on a healthy lifestyle by eating wholesome foods and exercising often.
Values - I eat food to fuel my body. I do cardiovascular activities to make and keep my body fit. I do yoga to keep my body strong and flexible. I enjoy life.
