There are a few resources that provide a different perspective. One I would suggest is The Power of Now, by Eckhart Tolle. As thinking, analytical people, we should (grudingly?) realize that there truly is nothing other than this moment. And this moment usually doesn't care about your time on a foam roller... unless it does, in which case you get on the foam roller.
I think there's a problem for highly creative or mentally busy folks. We see so many possibilities, and perhaps we excel as many things we try. That brings a feeling of unrealized possibility that nags on us. We could be a good this, or that, or whatever. In some cases it might matter to the world if we accomplished it (assuming that ultimately even matters). But quite often, perhaps, the unrealized potential may not be worth much. So the worry about the time we should be spending to realize that potential can be dropped.
Not to belittle the "average guy", but we all probably know the guy that has had the same job for 10 years and who is SO happy to go home most night of the week - and especially to be there Sunday - to watch whatever game on his big TV. He's got the deadly but oh-so-tasty snack that he's blissfully unaware shorten his life with each mini-sausage. He's got a wife who appears to actually like sports and who provides the snacks for him and his buddies (not being sexist; just painting a typical American Dream picture). His big Ford F250 4x4 parked outside is only 1.5 years old. Life is good. If he's really rich and bad-ass, he's got a new Harley in the garage for his every-other-weekend-warrior needs.
Meanwhile, the HN crowd is browsing high achiever Github projects, considering their own many ideas, and feeling like underachievers. And eventually we die, or we set off on the ocean like Jim Gray (https://en.wikipedia.org/wiki/Jim_Gray_(computer_scientist)#...) and never return.
