Mark O’Connell: “I’ll start a book, get about halfway through it, and then, even if I’m enjoying it, put it down in favor of something else. … On my bedside table, there’s a precarious column of half-read paperbacks that taunts me with the evidence of my own readerly promiscuity. The reason I don’t finish books is not that I don’t like reading enough; it’s that I like reading too much. I can’t say no.”
