This is a great thread, and I really appreciate everyone's insights.
Annie: specific example - Marc Allen, who first penned the "In an easy and relaxed manner..." preamble because he knew that he himself didn't have the drive to will himself to get results! If you haven't seen or heard his Millionaire Course, you should check it out.
Everyone: Each of our brains is unique in its genetic composition, cultural norms, and personal experience. The right way to phrase intentions will vary for each of us. From my experience and what I've read, MY intentions need to be believable TO ME, and specific enough for the universe to respond to in ways that I WILL RECOGNIZE. That leaves wide latitude for "your results may vary"!
Cheers,
Mike
