Hi Zak,
I agree with AlexK. Enjoy PR, and play with it. You don't have to master every step before moving on to the next step. Just run through the lot, with a playful attitude and be kind to yourself.
Before I bought PR I said that I had 4 weeks and wanted to master it within that time. I was told that the idea was to play with photoreading, and to enjoy it not to "master" it. That sort of thing comes later. Go with the flow and enjoy
