I'm only an M-1, so I realize it's a little premature to be thinking this way.
However, I'm not too sure I would do it again.
I worked for six years as a Firefighter prior to med school. As far as I'm concerned, that was by far the best job/lifestyle I've experienced. It was challenging, rewarding, and I enjoyed going to work every day.
Why did you leave, then? You ask.
I guess sometimes you think the grass really is greener, so to speak.
Anyway, I digress...
There are times I really enjoy med school (anything clinical), and there are times I loath it (didactic b.s.). I get good grades, and have a decent social life, but I just really don't enjoy preclinical medical education at all.
So I guess my answer changes day to day. I'm hoping that when I get to the clinical years, things will look up, and I will end up happy with my decision.
