I found this blog about people who get literary tattoos. It's funny how many of them like e.e. cummings, The Giving Tree, and Le Petit Prince. What do these things have in common, really?
But my favorite is one to which I can relate:
"I write for the same reason I breathe; because if I didn't I would die." -Isaac Asimov
Actually, I would never have this tattooed on my arm. It seems grammatically incorrect.
I don't know that I would have words tattooed on me at all. I worry that they would seem dumb after a while. (What would, "Jesus loves you and so do I" look like after twenty years? What if the Jesus-like lover became a cynical bastard over time?) I don't worry at all about pictures or symbols, though. I have no explanation.
