The more you do this, does your mind physically make connections between one part of your brain and the other? Also, I doubt it would have taken 6-8 sessions, simply because it wasnt that long of a book. if they are 30 minute sessions that would be 3-4 hours and that would probably be the normal reading time for the book. Maybe I didn't do enough sessions though, im not sure. And I don't completely understand mind mapping.
