Reading, like all work, has its rules. A perfect knowledge of a few writers and a few subjects is more valuable than a superficial one of a great many. The fine points of a piece of writing are seldom apparent at first reading. In youth, one should search among books as one searches the world for friends, and once these friends are found, chosen, and adopted, one must go into retirement with them. Intimacy with Montaigne, Saint Simon, Retz, Balzac, or Proust would be enough to enrich one's whole life.
