I recently purchased the photoreading tapes - I can enter the state and photofocus - but I find it relly hard trying to determine what my purpose is. Let's say I'm trying to read a single chapter in a history book about WWI - or the COLD WAR. Let's say I have no prior knowledge to these events, and all i know is that they are in fact WARS. What would my purpose be then? I'm always shaky as to what my purpose should be.. Sometimes I end up stating a few purposes, not quite sure which one I should be thinking of.. Even if i preview the chapter first - what makes a purpose sufficient? -- i feel like maybe my purposes aren't purpose enough - and maybe i should start hitting purposes thatll strike me emotionally somehow - im not sure. What's an example of a sufficient purpose for a history chapter?
