In the corona situation, I switched to breaking almost all deadlines - what is not possible is not possible. No weekend work. I work from 7am to 2 PM. If that means loosing my job, then that is it. But the outcome was different: I did not loose my job - others quit, because they could not stand the pressure, but I kept healthy and produced stable, ongoing work. Slower than everyone else, but higher quality (this is subjective, of course). I reduced my contract to 75% time (30hrs), which also helped. My compromise: No security for long term employment and no money saved. We do everything by bike, no car, no travels outside the country, no restaurants etc. - really everything cut down to the bare minimum. This is fine and it works for us/me, but a lot of PhDs in our department have higher expectations and I think they are better to pursue their career outside science. Look at how scientists worked a century ago: Their life was often equally precarious, but still their motivations helped them sustain constant progress.
