Yeah, physician/doctor isn't on there.
Which makes me think that the survey is full of shit. Yes, it's an expensive education and a difficult one. Yes, it's stressful and not every day at work is a cheerful one. And yes, we get bashed from all sides periodically.
And you know what? I don't give a fuck if we do. I don't lie awake at night wondering whether I've wasted my life (if you don't count the time I've wasted playing with cars, playing in bands, and chasing women, that is) What I do is necessary and appreciated. It's been a decent living. I don't have to apologize to anyone for how I've spent my life as a doctor.
So the survey is a pile of crap. Just my humble opinion, gently expressed.
