Forums IMPORTANT: PLEASE READ PhotoReading, Memory Optimizer I'm still having difficulties with all the process

Hi,
I am also brand new to this forum. So new that I haven't even started the program, only heard about it. I am very impressed with Leo's accomplishment here so I would love to get started. I would like to know if it is really necessary to buy the CD program or can one learn this just from the book alone? Please, advise me!
Thanks!!!
