I was browsing through the PhotoReading book last night and came accross a point that is worth repeating.
After PhotoReading, and before activation, postview the material, and come up with questions that you are *curious* about. Conintue to be curious, and fight the temptation to jump right in and get the material.
For, it is the curiousity, and the desire to learn more, that stimulates your brain. This stimulation creates more neural pathways to the information stored in your brain, leading to better, and possibly spontaneous, activation.
