Yes, like that. Your mind's eye snatches a word that appears to be significant to your need or interest. Could also be words in bolds or italics that catch your mind's eye.

You are looking for that 20% of the book that carries 80% of the meaning. If you have a 200 page book, then you are dealing w/ only 40 pages. Telling yourself that will help your mind find the significant words and text.

good luck
