You are right. The little blue PhotoReading book is excellent. It explains the whole process of PhotoReading in full detail.
The real difference between the book and the self-study course is, everything you read about in the how-to book comes alive as you go through the 8 instructional audio tapes and workbooks.
Think of it this way....the progress you may make over a number of months with the how-to book can be made in a number of weeks with the homestudy course, or just one weekend in the training seminar.
Either way, you're always welcome to come back and mine this forum for questions and answers!
