I hope (and I do genuinely hope, I'm not being sarcastic) that you are able to maintain that type of schedule/lifestyle for several decades. One of the reasons for burnout in EM (and lots of fields) is that students enter the field in their early/mid-20s and they're young, dumb, and full of . . . energy. Especially the single ones, who don't have many real-world responsibilities by which to be tethered.
Then you get married.
Then you have a kid.
Maybe you have another kid.
Suddenly you're 40 years old and longing for a different pace. If you're fortunate, you've paid your dues with whatever group you've joined, and are no longer stuck working all the night/weekend shifts. And hopefully you continue to balance your work with your life in a way that is meaningful and enjoyable for you.
I only say this because I understand how easy it is to be blinded by youthful ambition and vigor. As a pre-medical student (and even as an early medical student) I was so sure I was gonna be an orthopedic surgeon for the rest of my life. I was an athlete all throughout school, I thought operating all day was awesome, and the idea of being "the guy" everyone depended on at any time of day, any day of the week sounded so badass.
I'm a non-trad student, so my timeline is a little different than some younger guys. Life continued outside of medical school, and I started to realize that as much as I had idealized being an orthopod (or a surgeon in general), I would be absolutely miserable in 8-10 years, if not sooner. Thankfully, I ended up selecting a field I like just as much (if not more) than ortho, and it will have much less of a stranglehold on my life.
Anyway, I didn't mean to turn this into all about me. Just trying to share a few bits of wisdom.
