is not an ego-boosting appendage but a research tool. Read books are far less valuable than unread ones. The library should contain as much of what you do not know as your financial means, mortgage rates, and the currently tight real-estate market will allow you to put there.

Indeed, the more you know, the larger the rows of unread books."
