Well, it's been a long journey for me, but there have been many factors outside of school. In reality, for me, school was the easy part--and it wasn't always easy. I am formally at the crossroads now. It truly is now or never. I have no aspirations for neurosurgery or the like--not that there is anything wrong with that, but, even if I wanted to pursue that, it's on the greatly improbable side of things. Plus, having worked with many surgeons, and generally getting along with them quite well, I feel like there is one heck of a residency-fellowship road, and with perhaps a very few exceptions, should be started early on in life. Again, with some exceptions, it's not the kind of path for most career changers--physician wannabes. I mean they get beat up pretty badly after it's all said and done--and it is a longer, harder road that most other paths in medicine. That's part of why I give them much respect.
I guess I am wondering why you are looking at what other people are doing rather than what you are doing--i.e., what is within your locus of control? I mean there is a person I know in med school right now who could be my kid. So what? I hope the best for her. Her life track and choices were different than mine--for a number of reasons. It's not really relevant to my life. I could care less if she were a fellow training me in years to come. In fact, it'd be kind of cool. I can learn from anyone. I am open to it, so long as there are no ethical conflicts. And then again, sometimes it's about learning what not to do.
Have you applied to MS? Are you a re-applicant? I mean my situation has to do with the hoops and doing them with perfection, so I have yet to apply. At some point relatively soon, however, I will just have to jump, regardless of whether of not all the conditions look perfect.
Maybe you have to just look at what is working for you, and what is not working for you. Give yourself props for the former, and adjust or recreate the latter to the best of your ability--and then jump.
