I definitely don't like to hear that some steps must be religiously followed as taught. (photoread4me, where are you!??? JK

)
It's just that at least for me, I work best when I do things most comfortable personally. Otherwise, I resist. If I wanna activate right away, then heck yeah, I'll do it! Haha. (I'm not saying I always act on impulse, though)
IMO, PRWMS works best in a general way, so you're probably right about dispelling the myths(if they are). If it's so natural, then you don't require strict rules.
I don't go too crazy about trigger words. Besides, if I read books on the same topic, then that wouldn't be as necessary every time. Basically, I dip in accordance to my purpose, and my hunches work just fine. I feel that I can do this because I imagine what words my purpose would associate to, kinda like imagining a mind-map. Sometimes, though, I definitely look for "interesting" words before I delve deep into it.
Relaxed state!? Well, truth is, everyone gets relaxed at different speeds than others. I meditate for a bit and just go wit the flow. I personally tend to notice any emotional or bodily discomfort with internal visual cues, and dispel of them or soothe them, kinda in a Qigong type of manner. It doesn't always have to work to PR, though.
I must say, Mind Maps are super at some things, like dream recall. I write one key word, and all these associations pop into mind. I can't stand to write "every little detail" in my dream journal, as traditionally taught, unless I'm making a finished product.
I think the PRWMS is taught the way it is because it's easier to comprehend the steps. But it's best not to stop there.
