Keep PhotoReading with the intention that you get the information out of the book that satisfies your purpose. If you feel you're not getting the results you want, guess what? Your mind is probably wandering off.
What to do to fix? Just PhotoRead 5 to 10 books a day for 2 to 3 months activate at least one of those books per week.
How does this help? Training, confirming your intention that you want to get the information out of the book when you PhotoRead. Does it really take that long? probably not but if you're a PhotoReader just about everything that comes is readable that comes into your vision you will use the bulk of the PhotoReading skills to tackle. Does PhotoReading 5 to 10 books a day seems like a lot of work? It shouldn't and it won't in time. When you know how to PhotoRead the thought of PhotoReading 5 - 10 books in a day seems natural, not an issue naturally you don't need to do it every day.
My Purpose never was to become a profient PhotoReader. My purpose has always been to get at that useful information quickly.
