This is the tattoo I'm thinking of getting. I keep drawing it on (but the pic above shows it drawn in on photoshop as this makes it clearer for you to see!) to make sure I don't go off it, which to be honest is unlikely as I've wanted one for a year now. Personally I'd rather write it on and then get the tattoo artist to go over it so its not a font and no one else can have the same, also it makes it more personal. For me it would be kind of a personal reminder on my wrist. Now I just need to find somewhere to get it done!
