For computers use the X technique that' the easiest. Yes I do photoread anything and everything of moderate lenght it guides me to what is important in activation.

You are only going to have the information come up on a as you need it basis if you have done enough activation otherwise. Activation means to get active with your reading material asking questions pondering the authors ideas noticing what you agree/disagree with etc. If you don't do that then you inner mind has no reason to present the information to your conscious mind.

The more you activate the easier activation becomes. Even spontaneous activation is triggered with a sense of curiosity or questions.

Photoread 3 to 10 books a day and activate one per week for a couple of months helps to make the photoreading process second nature for you. Really applying it to all your reading material daily is what makes it easier to activate.
