This is certainly an interesting thread@!!
I see a lot of myself in some of these thoughts... from the past, when I was applying. It is all-consuming, and really encroached on my being. I thought (and my family was also telling me..) that it was important to not have many distractions from my ultimate goal; medical school.
Now I'm a third-year med student. And I see how important having a WHOLE life is. I can see some of my colleagues miserable because of what they've given up. And others happy to have something outside of medicine. Let me tell y'all... it doesn't get easier once you're in. In fact, it's necessary to have something to keep you sane. Something (friends, gf, family, etc) to tether your spirit to the ground, away from the nonsense of school...
I am happily relationshipped. It *is* a distraction. But without distraction, med school would really suck.
My caution: don't give up too much. You'll end up really embittered, and once you attain your "goal" of admission into med school, there's a whole new world of nonsense. (Then you have to honor Gross, then you have to kick ass on boards, then you have to honor surgery, then you have to kick ass on boards part two, then you have to match in a competitive residency, then you have to find a great fellowship position, then you have to find a top-notch attending position in a prestigious university, yada yada...) It only ends when you decide that it should. (for me, it ended with getting into med school)
Anyway, there's my two cents. Probably worth 1.5, with inflation.
