Are you a 'headbutter' banging your head against a brick wall?

In the supermarket are you the person who constantly changes cashier to find the fastest route? Or do you stick to your guns? "Think of those who, not by fault of inconsistency but by lack of effort, are too unstable to live life as they wish, but only live as they have begun." - Seneca Oh, and make your God damned bed. If you change your story, you can change your life.
