People working their hours in exceedingly challenging environment generally earn way more.
No they don't.
Early in my career, I watched coworkers work 80 hour weeks in pursuit of that next raise, or promotion, or the IPO payoff. I decided that I didn't want those things enough to kill myself for them, so I worked normal office hours, devoting my evenings and weekends to my family instead. At work, I worked hard. At home, I pointedly did not work (for the company).
And guess what...I was promoted, and earned those pay raises, just as fast as my overworked coworkers. My boundaries didn't slow down my career one bit. And those coworkers *respected* me and my decisions, and some changed their habits as a result.
No, the "work long hours to get ahead" trope is a myth. All it actually does, is burn you out, or in your story, kill you.
