John; I think the reason you were having problems and not being able to recall anything is because you did not have a purpose.
Activation will not work without a purpose.
"try again last year but i cannot recall any information after the books, i thought i have done the right step but confused why I have not comprehen information"
You will not recall information after photoreading the way you would recall information with conventional reading.
Remember Paul Scheele states in the photoreading book after photoreading you will have little if any conscious memory of what you just photoread.
This is why your purpose is so important to successful activation. If you have no idea of what you want from a book you are just wasting your time. You have to have a purpose, a goal of what you want.
Two things pretty important to your purpose are Why? Why do i need this information and so that i can do. So that you can do what? Answer these 2 questions Why and so that i can do and you are well on your way to having a purpose.
