That would require a photographic memory. After you read you have to do something to jog your memory- you use the book and questions (that you make up yourself that have meaning to YOU) to do this.
I'm beginning to believe that the problems people are having with PR are PRE-EXISTING memory or concentration problems.
The way I look at it is if I read something and I don't "get" something out of the book, then I really don't care about it, so heck with it. Since I only spent 5 minutes with it anyway, that just multiplies the "who cares?" attitude. And since at anytime I want to go to a book and activate it for whatever I want out of it in a few minutes, my "WHO CARES?" philosophy becomes, yes, CAPITALIZED... OOOOOOOOOOOOOOOOOOOOOO !
