I read gp’s formulation differently: “if you’re working 17 hours a day, you’d better stop soon unless you’re doing it for the love of doing it.” In that sense it seems like you and gp might agree that it’s bad for you and for your coworkers if you’re working like that because of external pressures.

I don’t delight in anybody’s suffering or burnout. But I do feel relief when somebody is suffering from the pace or intensity, and alleviates their suffering by striking a more sustainable balance for them.

I feel like even people energized by efforts like that pay the piper: after such a period I for one “lay fallow”—tending to extended family and community, doing phone-it-in “day job” stuff, being in nature—for almost as long as the creative binge itself lasted.

Weird how we went from like the 4 hour workweek and all those charts about how people historically famous in their field spent only a few hours a day on what they were most famous for, to "work 12+ hours a day or you're useless".

Also this is one of a few examples I've read lately of "oh look at all this hard work I did", ignoring that they had a newborn and someone else actually did all of the hard work.
