In every case where I have worked with someone who enumerates a list of rules like this, I have observed:
1) that the author believes he is being highly original;
2) the rules are enforced unilaterally, and adhered to by the author at best grudgingly if at all; and,
3) whenever a superior tells you, "I'm an X person," for whatever X you like (people, no-nonsense, pure as the driven snow, bullshit-free-zone) you can rest assured that the opposite is the case.
