Ask HN: How to Work Fewer Hours?

The gist of this question is, what can I do differently so as to work fewer hours and have more time for enjoying life?

I'm the sole income earner and need to provide for my family. I find it difficult to put in all the hours I need to in a day. (Theoretically, I'm a salaried employee, but I also need to account for eight hours five days a week).

I want to be there for my family. My son built a game and would like to put it up on the internet. My wife has written a novel and it needs proof-reading, and so on.

I go to bed tired and wake up the same way. I am actively looking into improving my health. I did just get back from a vacation, but, well, needed a vacation from my vacation.

What can I do?

I haven't talked to HR where I work. Would that accomplish anything? (I am a programmer, and am in demand; maybe there isn't too much downside). Maybe I could ask to work fewer hours in a day -- but I fear that might mean I lose benefits. [I would expect to be paid less; I would have to weight the pros and cons].

Starting my own business -- I tried; it went nowhere. (I did learn a fair bit, high among it being that I can't stand marketing). And I don't have the oomph for a side-gig right now.

Looking for other jobs -- maybe. Suppose I did; are other employers likely to, say, let me work six hour days?

I did look into taking a stress leave. Here in Alberta, Canada, I could do that for a few weeks, and get something like half my income from the government, which honestly is great, but even though I wouldn't say money is tight, it would be a struggle to get by.
