I'm a fan of getting "Difference Maker" tattooed in block lettering across the top of my shoulder blades. I saw it on one guy and it looked nothing short of amazing.
That is a picture of what the Tattoo might look like. Just print it off and they'll definitely tattoo it on your back just like that totally off center.
By far the coolest tattoo I think I've ever seen, you'd be an enormous stud if you got it VOL.
