Work just gets so unproductive past certain point that you're just doing it to signal others how hard you're working. I had a boss in academia who insisted on having a "5 minute meeting" at 4pm. We'd be scratching our heads at one of his stupid problems still at 7pm when he'd announce he has to leave because he has a family. Usually without exception you'd solve the issues in a minute the next morning after having a good sleep. I find there's like 4 good hours in the day for actual valuable creative work. The rest can be useful for grunt work, but there's rarely so much critical grunt work that one should exhaust themselves.
