From Book by Book: Notes on Reading and Life, by Michael Dirda.
The rapport between a reader and his or her book is almost like that between lovers. The relationship grows, envelops a life, lays out new prospects and ways of seeing oneself and the future, is filled with moments of joy and sorrow; when it’s over, even its memory enriches as few experiences can. But just as we cannot physically afford to fall in love too many times, suffer its gantlet of emotions too often and still remain whole, so the novel-reader cannot read too many books of high purpose and harrowing dimension or do so too often. Burnout, a failure to respond with the intensity literature demands, is the result. As with a love affair, the battered heart needs time to recover from a good work of fiction.
