Perhaps the best way to get started is to buy the book - I assume you have $$$ for the book.
Go through the exercises. Practice. Read everything you can put your hands on using the PhotoReading process. The library doesn't cost you anything.
Just because your friends haven't heard of PhotoReading doesn't mean YOU shouldn't explore it! Get curious, do your own investigation and evaluation.
If you want to make a million dollars don't talk to people who earn $40,000! Same here - if you want to learn about PhotoReading talk to those doing it, not those who haven't heard of it!
I think you'll be very happy once you've gained the skills of PhotoReading. You'll read more, open up new vistas, remember more and enjoy the richness reading gives you! Go for it!!!
