What about legalities?
That is a question I would like an answer to. Can I charge? Can I give away the book and then elaborate on the content? Can I teach the principles if I don't use the term GTD? (David did say they are "universal" and "glorified common sense.") Can I teach the content if I charge only for my time and give proper credit for anything that has a copyright for content? What is my time worth, then?
I wish I knew where the boundaries were. I would like to pass this on to a few groups I know, and I want to do it right - but it would take some time on my part to organize. It sure makes a difference being able to coach someone, versus having them only read the book.
TIA,
Gordon
