Coming from a medical family, I was also indoctrinated by my parents (and grandparents). But when it came time to choose a university course of study, I decided that medicine would be the absolute last thing I would do. I worried that I had been brainwashed, or that I simply felt pressured to go into medicine. However, I always wanted to be able to do at least two things with my career: to solve problems now, and to work on making the future better (scientific research). I later discovered that my initially chosen career path would only allow you to do one or the other, so I re-examined medicine (which I knew would allow me to engage in both), discovered that I really did enjoy biology and the clinical environment, and went for it.
As much as I love research, I discovered in graduate school that I would grow disgruntled over feelings that the fruits of all of my efforts were incredibly far off. I want to know that some of my work goes toward helping people here and now. If forced to choose, I'd rather put more of my effort into the "here and now" - but who knows? Perhaps I'll grow frustrated with many parts of medicine, and will transition yet again to full research...
So here I am, summer between first and second year of medical school (the "last summer vacation of my life") and I find myself in yet another immunology lab, logging countless hours behind a flow cytometer once more...
