I am salaried and work between two hospitals. Right now, I'm generally working about 50/wk, which is far better than it used to be earlier in my residency. I often find myself at home prepping more stuff work... So maybe I'm closer to 55/wk. I'm lucky to now be regularly getting 2 days off a week, though often times I'm on call for consultation. I actually had all last week off for Hanukkah, with the exception of 2 days on call.
I am however also involved with a startup though too. Recently, things have been taking off and I'm spending probably another 15-20 hrs a week on that. Thankfully I'm not in charge and don't have a ton of responsibility falling on my shoulders at this point.
70+ hours a week.. I guess it sounds like a lot. Considering I've never dedicated too much of my life to sleep (at any point in my life), I suppose it's okay. Work gives me purpose, purpose makes me happy, and despite lots of work, I still find time for myself, significant other, friends, etc. I hope my effort now will pay off later down the road too
