Sign is a four letter word.
Think about what your signature means. It is a promise. A commitment. A concrete, permanently visible action that you are standing by the words you are signing your name under. It is a mark saying you have read something, and that you will abide by that.
What do you think of when you sign something? Do you scribble your name, in hopes to get it over with? Do you read what you're signing? Or do you think what that signature means. Do you ever look at your signature on a document later?
