My experience was similar to Michael's. I was all gungho on the first go-round but my expectations were very unrealistic. I expected to be able to PhotoRead a book in 5 minutes and (20 minutes later) know everything in the book. As I went through the tape set, I tended to discount things that didn't support this unrealistic goal.
I had limited success practicing after that first listening. I worried too much about the process. I tried too hard.
I then went back and listened to the tapes again. Wow! The second listening made a huge difference. I heard so many new things that made so much more sense now that I had played with the system. I began to relax. I began to develop realistic expectations. I began to have fun with the process.
That made all the difference in the world.
