Some of China’s '996' tech tribe quit, seek less stress
Personally I can't do more than 2-3 hours of genuine "deep work" per day. That is high quality, focused, immersed thinking on a difficult problem and writing code.<p>IMO people who work a large number of hours each week get cognitively slowed. They can't tell they've slowed down (partly because they don't have a control to compare against) and so think that if you do 80 hours per week you'll do twice as much as if you do 40 hours per week. You won't, you'll do less.<p>Executives who think the best way to measure business performance is by how much your employees are sat at their desks are idiots.
