summarize the methods briefly?

90% of everything is hypnosis, NLP, or the law of attraction -- and in a very significant way, they are all the same thing "under the hood", at different degrees of modeling detail and with different preferred operating channels.

NLP has the most precise models, and the greatest emphasis on well-formedness criteria and testing. (At least, the founders had those emphases; "pop NLP" often seems to not even know what well-formedness is.) Hypnosis, OTOH, is just a trancy-form of NLP, LoA, or both.

Pretty much everything in the self-help field can be viewed as a special case, application, or "tips and hints" variation of one of those three things, but using individual authors' terminology, metaphors, and case histories. The possible failure modes are pretty much the same across all of them, too.

There is, by the way, one author who writes about non-mystical applications of the so-called "law of attraction": Robert Fritz. He's the only person I'm aware of who's brought an almost-NLP level of rigor and precision to that concept, and with absolutely no mystical connotations or bad science whatsoever. He doesn't call it LoA; he refers to it as the "creative process", and shows how it's the process that artists, musicians, and even inventors and entrepreneurs normally use to create results. (i.e., a strictly mental+physical process that engages the brain's planning systems, much like what I showed in my video, but on a larger scale.)

His books also contain the largest collection of documented failure modes (biases and broken beliefs) that interfere with this process, based on his workshops and client work. I've found it to be invaluable in my own practice.

(The biggest shortcoming of Fritz's work compared to some more mystical LoA works, however, is that he doesn't address general emotional state or "abundance mindset" issues, at least not directly.)
