First, always look for any pieces of evidence that PhotoReading is working for you. The dictionary game is a good start. Think of anything else that could be attributed to PhotoReading. Success breeds success.
It is not uncommon for a PhotoReader to get the dictionary game at first. I don't know for sure what happens next, but I suspect that you were putting too much pressure on yourself and not paying attention to the signals that were coming up. You were trying too hard. Or, trying to "left brain" it. Don't worry about it--it gave you your first successful PhotoReading experience. Now it is time to go on to the stuff that matters.
Usually, when a person does not have success from PhotoReading, they forget that PhotoReading is not like regular reading. You do not get conscious comprehension as you PhotoRead a book. Sure you may experience spontaneous activation, but that generally comes from people who PhotoRead 5-10 books a day for a couple of months (PhotoReading, that is, without activation). When you have the first and the second and the third experience of spontaneous activation, it is much easier to have the the fourth, etc.
For people unwilling to spend the time to PhotoRead that much in the early months, you have to fully activate a book as is said in the PhotoReading book, the home study course, and the seminar.
If it takes you 10 hours to read a book regulary, you should spend about 1/3 activating the material. To better understand activation, and what can happen during that 1/3 of the time, go to the PhotoReading section of our main website and read the article called "Works on all material."
Then get a nonfiction book of about 250 pages, follow the system with the insight from that article, and tell us about your experience. We can pick it up there!
As far as riding a bicycle. For many people it is, but it depends on a lot of factors such as a person's confidence. That's where some of the Paraliminal Tapes such as Belief and Self-Esteem Supercharger and Personal Genius can be beneficial.
