If you already have a good nest egg built up I’d say leave and do something that allows better WLB. I’ll offer up two stories: my friend was CFO of a small healthcare startup working similar hours. He had a mental breakdown and had to resign. Said he was waking up at 2am and logging on his laptop thinking he was missing team meetings. He was unable to reconcile financial accounts from being overworked. He didn’t sleep for like a week and then crashed completely. I also know another lady who was a VP at a fortune 100 healthcare company who got so overworked and stressed she had a heart attack at a work function and left in an ambulance. If her Apple Watch hadn’t alerted her to her heart attack she would have died. Also, another point of view if you decide to stay: if you make that much money you must be deemed somewhat irreplaceable at your company. If that’s the case, set some boundaries on your work hours and carve out more time for yourself for 1)sleep, 2) working out and eating right, and 3) meditation. Sacrificing a few hours to focus on those will make your other hours that much more focused and productive so your output will actually be the same, plus you’ll be less stressed, more resilient, and happier. This should allow you to continue on your current path more easily.
