I do agree that’s the best takeaway from the article. The long hours do creep up on you. I can’t tell you how many deep debugging issues were only solved in the first few minutes of the next day only after going home. Similarly I've been in and seen hard working teams make chains of silly bad decisions that had to be corrected with even more work later. So I guess keep in mind the corollary is that it’s a marathon not a sprint. And maybe so it’s less of a trope: there is “too long” on both a low level everyday as well as a larger scale - come up for air and breathe and get your bearings and perspective.
