This quote means that reading literature (books, poetry, etc.) is something very enjoyable for someone to do, but reading fiction (novels, mysteries, etc.) is something that everyone needs. Reading can help us learn about different cultures, push us to think about important issues and even provide an escape from our own life. Fiction is especially useful because it encourages us to sympathize with other people’s experiences, to learn how to come to terms with our own problems and to relate to a wide variety of characters and situations.
