"The second suggestion is to think as well as to read. I know people who read and read, and for all the good it does them they might just as well cut bread-and-butter. They take to reading as better men take to drink. They fly through the shires of literature on a motor-car, their sole object being motion. They will tell you how many books they have read in a year. Unless you give at least 45 minutes to careful, fatiguing reflection (it is an awful bore at first) upon what you are reading, your 90 minutes of a night are chiefly wasted."
