A couple of rules.

The first rule of discovery is to have brains and good luck. The second rule of discovery is to sit tight and wait till you get a bright idea.

The first rule of style is to have something to say. The second rule of style is to control yourself when, by chance, you have two things to say; say first the one, then the other, not both at the same time.

The first rule of teaching is to know what you are supposed to teach. The second rule of teaching is to know a little more than what you are supposed to teach.
