When we’re under pressure to get things done, our feelings of anxiety, frustration, and anger about what’s wrong trump any feelings of appreciation, even if, upon reflection, we really are appreciative. Over time, appreciation deficits set in. And these often become two-way: I think you don’t appreciate all I do and all I put up with, and you think I don’t appreciate whatever-it-is you do. Call it Mutual Appreciation Deficit Disorder (MADD), and you have the ingredients for a troubled working relationship.
