"In my experience, long hours may actually be predictive of poor future results." Reminds me of the WWII story about discussions to add more armor to planes that came back from battle where the holes in plans were, when someone pointed out there was no need to armor *those* places, those planes came back. Where armor obviously needed to be added was to the places where the surviving planes *didn't* have holes.
