If you have the skill set that can garner $1.5M I imagine you can probably do something in between your current job and this one that doesn’t sound like literal Satanic punishment.
If the 2 AM grind only lasts 2-3 years then you enter a management type role where you’ll be doing normal business hours then sure, take that. But you said 10 years? That’s about 1/5 of your adult life. Doing something you’ll come to hate with people you don’t Ike much.
