I've thought the same thing about tattoos for decoration, but there are other approaches.What has always gone through my mind is...I'm going to have this image on me FOREVER...and I don't know if I'd like that same image 20 years from now, as I might right now. lol
My own tattoo is mainly a message to my future self. It's a reminder about lessons I've learned and don't want to forget... if that makes sense.
My favourite tattoo story is in Moby Dick: while in a port on the other side of the world from home, a sailor sees an enormous whale skeleton. He's so impressed by it that he wants to bring word of it back home. He knows he's going to be at sea for several more years, so he doesn't trust any paper record to survive without being destroyed... so he gets the skeleton's dimensions tattooed on his arm. When I read that, I thought "that makes sense."
