Occasionally you get someone who offers counsel with only a few words, yet those few words can open a door to knowledge no encyclopedia can fill.
I had a great teacher who coached me on becoming a facilitator and he offered some short insight that has helped me more in the area of facilitation and just about everything else. His words were as follows: "The only rule book you need is the one inside yourself. Once you get in touch with that, all the other rules fall away." And it's true for when I can get in that place, it sets the stage for right thinking and right acting in the moment. Of course, it's not always accessible - stress, frustration, and competing agendas always seem to want to crowd in, but in in establishing a sense of knowing the feeling, thinking and acting that tells you when you are there provides an option that transcends the normal rules and still keeps me in touch with the tools and techniques I need when I need them.
