That's what I would say 99-rules too many!
I have only one rule:
1- Use your head!
OK, ok, that's a simplistic way to describe it, but that's really what project management is all about, using one's intelligence to plan a project and solve all those unpredictable situations you will be faced with.
There's also a plus: if you apply my rule #1 you are surely going to come up with your own, personal, custom-made 100 rules! And you don't need to trust NASA, after all they have failed projects - you don't want that! (or do you...) ;)
