Quirky Tracking?

So I have developed an interesting way of tracking my success and was really curious to see what other's may do to keep themselves focused or motivated.

My crazy method? I have an awesome tattoo on my arm...

I got it to remind myself that I am not trapped in my food issues, God has led me past it to better things. Problems is, I haven't lived like that. I recently realized that there are 40 little parts to my tattoo. 40 days is pretty significant in the Bible, so I decided to work on going 40 days without binging or overeating. Tracking? Why, I'll just color in my tat!

A little Sharpie every morning and I've got a great reminder right on my arm of how many days I've been successful.

So, anyone else have some goofy, fun, quirky ways of encouraging themselves to stay on track?
