But isn't this article saying the exact opposite of this? It may be counter-intuitive, but every serious study I've seen regarding the amount that people work consistently says that 40 hours (or less) is ideal, and exceeding that for an extended duration (where "extended" is a very small amount of time like a few weeks) leads to negative productivity. It seems like there's often a lot of cognitive dissonance going on in these threads - when we're talking about managers or people other than us telling us to work > 40 hours a week, it's widely accepted as counterproductive, but when we do it ourselves, we ignore the data and revert back to platitudes about pushing yourself harder and not being complacent.
