The first book I ever photoread was DeBono's Thinking Course. I followed the directions in the Einstein Factor. Man, did I want PR to work!! I was too lazy to preview or to activate back then, so I just photoread and slept on it under my pillow (I had just read Edgar Cayce's Biography).
I wanted it to work so bad, that my dreams were in utter torment. Asleep, I was FORCING myself with all my mental might to reproduce the book in my dreams. I saw myself flipping the pages as I had done before bed. When I awoke, I remembered, THAT every morsel of knowledge within the book was available to me and that I had read the entire book in my sleep. But consciously, I remembered nothing. And though I had slept for 8 hours, it was of absolutely horrendous quality. Not an altogether pleasant experience.
Maybe I was Direct Learning how to think? There's a thought! Direct Learn 5 or so of DeBono's books on thinking!
That's what I did with 3 books by Mihaly Csiksentmihalyi and Natural Briliance--my purpose was to live in the flow state 24/7. ...I have a tendency to think big...perhaps I was expecting too much?
