Okay, here's the kettle preaching to the pot. Relax, trust yourself. Go through the 300 pages in 10. If you get through in 2 minutes and never dip, well so what you've only wasted 2 minutes.
Really, use the layers. Short dips. Read ideas not words. Dip for no more that bla seconds (bla is a cop-out make it 10 s). At the end of the first pass you may only be able to write a few phrases that don't seem related. However, with additional passes it starts to come together. Some say that it's start making sense on their third pass.
Okay, that's the course line. Well except for the 10 seconds. I personally need more work with layering. I tend to do a single pass, however I'm happy with what I learn in the single pass.
Good luck on learning to layer,
