Can we get some attending viewpoints? Especially the ones who are 50-60 years old. Really respect the old school type of docs.
My 2c: Ron Paul is a good example of a doc who is able to do more than just be a doc. You can have more than 1 career if you want to.
OK, I'm not 50 or 60, but as a graduating resident getting ready to start into attending-hood, here's my view:
Every field will have a distribution of people who love their job and people who hate their job, and everything in between. I like what Law2Doc said about the maxim applying specifically to careers that aren't prone to "dabbling"; I think there's a lot of truth to that.
I had a prior career (musician) that spanned the decade of the 90's, and now a medical education that has essentially spanned the decade of the 00's. It has been my good fortune to love each of these jobs for various reasons, and to end up in a specialty that I imagine I will be happy in until I am an old man. But it definitely hasn't come about without the requisite "pound of flesh".
Why do people burn out or end up hating medicine? There are a lot of reasons, some more cynical that others. Some may not have been honest enough with themselves about their own motivation to enter medicine. The thought that one's motivation may be more financial than service-centered isn't a comfortable one to entertain, but I can guarantee you that, in a private moment, virtually everone in the field has asked themselves that question. Other people may have a preconception of what medical practice is that doesn't line up with the reality they experience. Part of that may be the selection of a specialty for which they are ill-suited. I can't stress to medical students enough how important this decision is, and how critical it is to take a brutally honest inventory of what you value in your own life and what you enjoy about medicine.
Ultimately, that statement is made as a pat way to alert applicants (and med students searching for a specialty) to the
commitment that medicine entails. I wouldn't say you have to love or be singularly devoted to medicine. I'm not. I'm singularly devoted to my family, and lucky enough to love medical practice. What you DO have to do is this: know what motivates you to enter the medical field (whatever it is), and keep that motivation front and center during your training. Keeping that center will help when you're at hour 35 of a 36 hour shift, or (as I will be soon) dealing with the minefields of billing, insurance etc.
