My suggestion is to go to your local book store or Amazon.com and order Tony Buzan's THE MIND MAP BOOK. By far, this is the best book out there for learning how to mind map, and it makes an excellent book to practice photoreading on as well. In fact, I believe that the Photoreading Personal Learning Course would be greatly improved if it included this book.
On Tape 6 I believe of the Personal Learning course, Paul Scheele guides you through a mind mapping exercise with the Photoreading book and the Natural Brilliance book that is quite helpful for people who have no experience with mind mapping.
Mind mapping is one of the most untapped resources and yet it is truly effective.
