Ya the other comments here are all good, but this is the one that resonates with me the most. As developers/makers/inventors, we can generally solve any problem or adapt to any situation. But it's the idea that we'll have to do that tomorrow, and the next day, and the next.. that really undermines my psyche.
If it weren't for the confines of the normal world, I could have automated or otherwise solved most of the issues I have to deal with. I could have written my own software to sell for residual income, or a library that helps countless other developers, or even a language with fewer or no foot guns so I could solve actual problems instead of putting out fires endlessly.
But instead I have to go to work each day to make rent. So my perception is that I have to spend 5+ units of work to free up 1 unit of free time where I could get actual work done. My best efficiency under the workaday world will likely never break (or even approach) 20%.
That said, I realize that my view as stated above is laced with negativity. I'm not seeing the benefits of civilized society such as the infrastructure that's already in place around us, or how inexpensive even high-tech goods have become. I'm ignoring the stochastic and emergent behavior to dwell on the deterministic. Which I believe is what's at the core of suffering in the postmodern world.
So I'm centering my focus on making work seasonal again. I think humans evolved to hunt and gather for 2 hours per day and store enough food to rest for 3 months. We're working about 5 times harder than we should, right at the limit of sustainable human endurance. A 30 hour work week would get us closer to 4:1. I'd also like to see more jobs where 2 workers do the work of 1, at 20 hours each. And at a minimum, we need far more businesses like Uber (no affiliation) where workers have full control over when they work and for how long.
Short of all that, meditation does appear to shift attention towards the reality where progress is happening. Setting boundaries appears to effect those changes externally. Metaphysics don't exactly follow physical laws, but I believe there is a harmony to them that can be modulated.
In my case, I reclaimed Saturday in my personal relationship as my hobby day and negotiated a 30 hour work week with 2 days remote. Now your current employer may be reluctant to do this, so you may need to flip things around and see their needs. You can build a team or find friend(s) to cover your hours (best choice IMHO), or pitch the reduced cost to them (rarely but occasionally works with small businesses). If your employer isn't motivated to consider your needs, then land a 30 hour position elsewhere and let them decide if they want to keep you. If not, no harm no foul, it's just business.
So far I've only set a couple of boundaries like this, and very recently. Working through that kind of growth can be hard but it's made a big difference. It's not the act that we get stuck on, but the ramifications. That's why I think that metaphysical practice is so important for getting unstuck.
