As I sit at my worn-out, old desk for the very last week, it occurs to me that I will miss the slush pile. It is the bottom of the publishing structure, designated to the bottom of the publishing pecking order. But it has taught me more than I could ever have learned. In order to know what works in publishing (the most important skill in an editor’s toolbox) one must know – deeply, know – what doesn’t work and why. All things are defined by their opposites, and good books are no exception. So as I walk away from Rockefeller Center, probably tearfully, it will be a comfort to know that although I’ve never collected a dime for my efforts and although I’ve spent my time here feeling intellectually inadequate by contrast to my coworkers I have added one hugely important skill to my toolbox.
