Books are everywhere; and always the same sense of adventure fills us. Second-hand books are wild books, homeless books; they have come together in vast flocks of variegated feather, and have a charm which the domesticated volumes of the library lack. Besides, in this random miscellaneous company we may rub against some complete stranger who will, with luck, turn into the best friend we have in the world.
Cram your head with characters and stories. Abuse your library privileges. Never stop looking at the world, and never stop reading to find out what sense other people have made of it. If people give you a hard time and tell you to get your nose out of a book, tell them you're working. Tell them it's research. Tell them to pipe down and leave you alone.
