Usually I can picture how I will look when I reach my goal, the clothes I will be able to wear, etc. I was having a hard time keeping my "eye" on my goal until I found LLBean's website and used their virtual model. First I put in my start weight, then my current weight, then my first goal weight, and then my ultimate goal weight with each of the models wearing the same bathing suit.
It really gave me a different perspective. To actually see a picture that is pretty close to what I will look like when I reach each goal. It also helped to see how far I've come! I would suggest anyone check it out if they need some motivation!
