"Now, my young friends, this habit of reading is your pass to the greatest, the purest, and the most perfect pleasures that God has prepared for his creatures. But you cannot acquire this habit in your old age ; you cannot acquire it in middle age ; you must do it now, when you are young. You must learn to read, and to like reading now, or you cannot do so when you are old." —Anthony Trollope.
