I've often found some trouble in picking up key words in books. I flip every couple of pages, flip about 15-20 then do a couple pages, then 15-20, etc etc etc.
I don't know really what is to be "key" in the book at that point and can only find say 8-12 out of 20-25 that is suggested. If I go through the book and can't find the amount I think I should have, is it reasonable to turn to the index and just pick up a few key words that seem to strike my interest, or that seem to be brought up throughout the book?
Just a simple question. Thanks.
