Hear, hear, Kathleen. My boss’s boss took me out to lunch recently to tell me to dial it down a notch. Her assessment (and I valued it: she knows a thing or two about over-achieving) is that my natural 80% –if I could make myself stick to it — would be everybody else’s 110%. I haven’t been perfect at this, but I’m getting better (which means saner), and that, too, is Enough.
