Way to go! I did something similar for something else. When I was in grad school and working full-time, I had a jar of pennies that I used to count down until graduation. Every night I came home from class, I took one penny out of the jar. Seeing visual progress is a huge motivator.
The closer I got to paying off my student loans, the more I wanted to pay them off. I ended up just writing a few big checks towards the end and got rid of them completely. What an awesome feeling it was to see that balance at zero. You will be there soon, too!
