Are you really efficient, too? When I see teams starting to work 60-70 hour weeks, I start looking for the underlying causes. Often, the system is just broken and people have to put in double effort to keep up. The data suggests that a typical person has diminishing effectiveness after 40 or so hours a week.

Working 60-70 hours is not something you should be proud of.

Talk about 1.5-2x output, and that’s something you should be proud of.

In Japan people “work” 80 hours a week, but a lot of that time is just keeping busy.
