The IBOS. Do you have any, and if so, what are they? I haven't read the entire thing yet (its ridiculously massive) but I just got done reading a chapter from it on Ethics and Etiquette, and I found it to be one of the most simple-yet-profound things I've ever read. The things the author wrote in that section are extremely true, and I feel humbled by it. I think all practioners, new and experienced, should read it.
