This applies to salaried or consulting professionals of course; if you're working your ass off to build your own business and maybe hit big rewards in the future, it's a sensible choice. Otherwise, you're just busting your health and personal life for somebody else's benefit. Which is only acceptable if you have no choice (really need the money, and don't have the market value to earn the same in a job with more normal dedication).
Many video game developers work 80+hr weeks for well under 100k.
The (perceived?) prestige of being a video game developer makes up the difference.
60 hour a week people haven't got that idea yet.
I always find these types of discussions interesting. It's never about things like work ethic, efficiency, or even skill, it seems to devolve in to what everyone thinks is the ideal work schedule for someone else. I have friends that think I am crazy for working like I am now. I don't really care, I am happy, the clients are happy, and my bank account is most certainly happy. But I would never tell someone else they should work as much as I do, or that they should only work 30 hours, or some other random number of hours.
I had to work a 90 hour week a few weeks ago to address a operational crisis. That netted me a bunch of overtime and a week off.
I think the "art of working" is deciding what kind of work you want to do, how big a part of your life you want it to be, and then doing that.
OK, I don't want to be overly cynical here ... but come on, if you read some of the stuff in our echo chamber ... just don't take yourself so seriously. I mean I know there ideologues are only in startups so they can one day build some utopia in which there is no such thing as money ... but come on. :)
