I've worked in Japan with the stereotypical salaryman "work ethic". I completely agree that it's toxic and horrible. Truly horrible. (I eventually rebelled and started leaving at 6PM, choosing to suffer the shame.) But now I've found working for myself 12 hours per day 5 days per week completely sustainable, enjoyable, and productive. I certainly never felt this way when working for other people though. I think what makes it work is: 1) No external pressure. I could work 5 hours if I wanted. 2) Comfortable as possible office. I truly can't think of anything to improve. 3) Being able to take a bike ride or walk whenever I want. 4) Probably most important: a deep drive to work on my project. I can't wait to get to work in the morning. This feeling only lasted short times when I worked for other people.
