The wonderful Mario Garcia graciously included me today in his list of good editors he has known.  When he asked me for my own thinking about what drove me as an editor, I said what I’ve always felt:  That your main job is to make everyone else’s job go better.  Another ingredient occurred to me yesterday, when I had lunch with a friend who told me that someone had once called her “the toughest nice person” he knew.  Definitely another good qualification.
