I have recently spent a huge amount of time contemplating this question. I know now that if I go on, I will get into medical school, and that I have the ability to do as well as most of my classmates. I think that many pre meds, non trads in particular, are so consumed by the desire to get into medicine, and by a possibly idealized image of what the practice of medicine will be like or what they themselves will be like, that they are either unable or unwilling to consider how and why so many people appear to be dissatisfied by their choice. I am sure everyone reading this, has spoken to at least one doctor or medical student that is rather unhappy, and at least one that says there is no other career for them. I look at documentaries like this - http://video.pbs.org/video/1114402491/ and threads like these: http://forums.studentdoctor.net/showthread.php?t=55501 and I feel so torn. So what do you guys think? Is there anyway to predict or classify those who do well with those who wish they had done otherwise? For those of you already in medical school, residency, or in practice as attendings, or who have left the field, how have your views changed?
