Work is not work. That’s a single data point. I can mention few cases I experienced: student learning last week for exam. 100 hours week is nothing unusual here. Of course it’s not sustainable and does not take longer than few weeks. PhD student writing paper for most important conference of the year - 80 hours week. Working for your own startup 60 hour a week is imho absolutely normal. These are cases for personal gain. Now let’s talk about salaried jobs when one gets paid for sitting in the office or be green in Teams all day. And that’s the case where 10 hours each week of actual work is absolutely sufficient. I am pretty sure that productive hours are proportional to gain. Why should I do 50 hours a week for the Big Corp when my salary will be exactly the same as after productive 15 hours weekly!? There are individuals, that like what they do, so they enjoy daily tasks and are productive closer to 40 hours weekly. Luckily I know few such people, they are very inspiring.
