If you aren't going to activate then just be sure to prepare and say heck with the preview. If you decide to activate later you can do a quick postview.
"I want this book to improve my PR skills." That's ok but I would ad more clarification and personalization. I think a whole new book can be done on Purposes alone.
Experiment with this:
Prepare (state, purp, relax, affirm)
Photoread
-sleep-
next day:
Prepare
Preview (gather Triggers, start a MM, or don't, Make mind probes, do whatever you want)
