I get almost all literature for my papers from libgen and scihub. I even have access to a lot or journals through my uni’s VPN, but it’s just much simpler and quicker to use the open seas.
My justification is that a) scientific journal publishers are evil and a scourge on humankind, and b) on average, I only need like 1% of the info in such literature, so I would never buy it anyway, which means that me pirating it doesn’t affect sales in any way.
I’m closing in on 40 and life satisfaction has been rising consistently over the past couple of years. I think the peak is still ahead.
