in 1955 George Miller discovered[1] human can only contain 7 bits of information at the time. Ie. if I write 1452687 and ask you to read it only once and then close eyes and repeat it, you will be able to do this. If I write 12573945 and ask you to do the same, you will most likely not be able to do it. Same happens with bigger "bits" of information: you can remember 7 ideas/statements from the textbook you read, so do not trap yourself in "ah that is easy, I will continue reading without taking notes". After every 7 "things" write them down, note the page number where they are and then continue reading. Otherwise it is a waste of time.
