I compare, side-by-side, the pictures of your past. Look at how you once were, and how you are now. I see the differences and the similarities. I get a glimpse of what you used to be, and a representation of how you are now. It's good to reflect on what was done in the past. To compare yourself now to yourself then. This can give you a better understanding of your growth as a person. This also gives me (or whoever is comparing) a better understanding of the one being compared. It allows you to see how their tastes and behavior have changed as they progress through life. It is truly interesting to see the changes from 5 years ago compared to today...
