Reading

Reading is human contact, and the range of our human contacts is what makes us what we are. Just imagine you live the life of a long-distance truck driver. The books that you read are like the travelers you take into your cab. If you give lifts to people who are cultured and profound, you'll learn a lot from them. If you pick up fools, you'll turn into a fool yourself.

-Victor Pelevin, The Sacred Book of The Werewolf
