Since this thread is discussing big books, I want to know how many trigger words should I find for a book that is over 1000 pages. I just photoread a 1500 pg ebook on economics. The photoreading book says that you should find around 25 trigger words for a book, but I find that there seem to be much more trigger words if I try a long book. How long should my postview be? I only picked out trigger words from the table of contents and did not bother to go through the entire book because if I did my postview might be over the recommended 5-15 mins. Is that still ok? And I find that I'm not picking out words but I'm getting phrases. Is there such thing as trigger phrases or should I just find words?
