Idk I calculated through my financial needs after retirement for 13 years (67-80) which would be around 400k€ and calculated through my savings I'll accumulate until then, if I keep up my current saving rate. I'll end up saving around 270k€ so ultimately I decided fuck it, Ill just take jobs where I can live comfortably right now and hope for the best in retirement. I take jobs that are fun to me. I have 37 years until retirement and will never be able to afford a house or whatever so I can switch industries whenever I feel like doing so.
