I was younger and didn't have kids yet. I couldn't do it today. I was probably 8 years into my career making I think around a 100k. I travelled for work every couple months, 11 days at a time. Those trips I worked 6am to midnight every day. I was so burnt I couldn't think straight. Prior to that job I was burnt as well, I just couldn't take it anymore. I was late 20s and felt 50. I called my wife from one of the trips and asked her to just start reading me the list of open positions at her company that were not tech. She mentioned one, I said that's it. Interviewed the next week, they offered me the job that day and I started 2 weeks later. It was try something different or be miserable. I was very seriously considering enlisting as well just to get out.
1) My brother died from a sudden illness (genetic, but no known predisposition in our family, e.g., unavoidable) in his 30's with four young children. Stress was really bad for this. Accepting significant stress and burnout now for only a possibly low-stress future is not necessarily a good bet or trade-off.
2) My dad was a workaholic because he was worried about money and retirement and being the "invaluable employee" when I was a kid. He worked often until late at night and on weekends. He came to lots of my games and stuff, but he always missed everyday life. Always. He and his mates were all eventually "downsized" from his high-paying job at a Fortune 100 when they sold off his software development unit to a competitor when I was a late teenager. He realized he fucked up our relationships and was fucked up himself by the lack of work-life balance, and took a job that was less demanding and of course paid less, but it was already pretty late by then. I was maybe 17 or so already. You can't get that back, and our relationship was never the same as when I was really little.
Anyway, a fat paycheck is nice, but there are other nice things in life too. I hope you do what is right for you.
I'm in a very similar position to what you were probably in and honestly taking a random office job does feel like the "right" choice here.
I could never stomach a 65% pay cut though because I have dreams/goals of someday not working at all. I save a significant portion of my income and live well within my means all toward a goal of retiring hopefully around 50 or 55.
One could reasonably ask why I am delaying pleasure now for pleasure then, but my answer is simple. While I am burned out and while I am struggling, I'm not sure I am struggling as much as I would be at 50/55, potentially battling some horrible illness, and unable to stop working or even cut back because I had saved so little.
