When you look at a typical office life it involves 9 hours of commuting a week, water cooler talk and meetings that don't go anywhere (but aren't much fun either), very few holidays and an email-based culture. This is for most people clearly sub-optimal, and yet it's often the lifestyle people kind of gravitate toward.
If you want to go about your week in a relaxed manner, that's great. Do that. If you want to work hard for 3 years and chase an exit? That's cool too.
I'm not sure what the real point is of the article, because most of the statements about "productivity" are straw men. The title of the post is "Stop being so fucking productive" and the only actionable advice in it is "become more productive by switching projects less often (because it reduces context switching overhead)". So this post contains yet another another strategy to improve productivity while pretending to be tired of exactly those kind of posts. Yawn. Except the productivity claim here is based on anecdotal evidence (even though there are a lot of research papers out there that need summarizing!).
