This is a great line. I think it goes deeper though, in that after doing this for a while, if it hurts, you are probably doing it wrong. Writing code with too little tests hurts, because you are scared shitless. Writing code with too many tests hurts, because you are performing a religious rite not actually building something useful.
The trouble is that you have to do this for a while to get to the point where you can both feel and recognize pain, or the lack thereof.
