Whenever we first set out to learn something we usually are forced to learn the rules of that particular activity before we’re allowed to fully engage in it. You don’t get a license to drive without first being able to demonstrate that you know the rules of the road; stop, go, yield, right of way. You wouldn’t send your kid onto a basketball court without first making sure she understands that she’s not allowed to kick the ball. Rules. Every now and then they’re useful.
