@GravelRider, you are one of my favorite posters, but I disagree. First of all, the vast majority of people entering medical school now, or finishing it, should never consider anesthesia, period, unless they can't get anything better. Now about the people already stuck with a residency...
People have to train for a particular regional market, at least for whatever they can foresee in its future. It will bring them so much more more happiness. Forget about passions, make hay while the sun still shines. The best job is the one that makes you more than enough money and allows for a lot of time off. That's the secret. It's almost always a partner job. Just read this forum if you don't believe me; most unhappy people are stuck in a bad employed position, and the other way round. Don't just follow your heart, passions and other BS. If the market rewards blue anesthesiologists with partnerships big time, go drink ink till you turn blue if you have to.
They say one should follow one's passions because it's much easier to do work that one likes. Guess what: people like to do stuff they are good at, so get good at what
the market wants, not at what
you want. One should do whatever is rewarded by the market with partnerships, meaning the subspecialties where demand dwarfs supply. Right now it's cardiac, and maybe pain, so that's what any intelligent person should do. Try to get into a great program and get good at your job, and do maintain all your general anesthesiologist skills for life. Happiness will follow. Just don't expect it to be permanent; this business is cyclical, and every cycle burns some people.
