I purchased PhotoReading because I was writing a book, and my yet-to-be-completed book has a chapter on Ontology. Because in Ontology one has to seperate what is real from what is not real, I knew I'd have to do massive amounts of studying on mathematics, philosophy, the psychology and neurology of perception, Platonic and Kabalistic mysticism, and perhaps on subjects I have not yet thought about.
I've discovered that PhotoReading works best when one reads for curiosity, rather than to become an expert at something. Curiosity may be satiated, or it may lead to confusion. Confusion can lead to further curiosity, which can be satiated in further activation. The need for experitise might also lead to confusion, but this confusion leads to fustration. Fustration happens when one NEEDS an outcome to occur, but that outcome does not happen. The 20th century English philosopher A. Crowley called this "lust for results," and spoke great ill of it.
The thing about PhotoReading is that you cannot get better at it by trying harder. You can only get better at it by trying softer.
