> Let's be honest here: rare is a person who can do cognitively demanding work 8+ hours a day for longer stretches of time. Especially when that's a job, and not one's true life calling. No one is capable of doing a full 8 hours of cognitively demanding work. I think Cal Newport detailed it out, but the most dedicated and focused people can achieve 6 hours of productive work. Most people can average 4. The 8 hours/day, 40 hour work week is a relic from manufacturing work that has carried over into the office. Between cubicles, open office layouts, meetings, the belief you have to be on premise to be productive, and the execs deluding themselves into thinking they're working the hardest, the US corporate area is not set up for productivity.
