I've never been told to pursue anything by my family, and my parents are typically easy-going in that respect. They let me do what I want. My sister hates doctors and b****s all the time about how "they don't know anything " (except when she gets really sick...then doctors seem to know quite a lot). They provide a bare minimum amount of encouragement, so I've found that I'm essentially alone. In fact, I can't remember the last time they asked me how my apps are going, which is relieving since this s*** is stressing me the f out. Even my friends who are applying to med school don't really give me a sense of community, as they're all in different circumstances (they went to schools with 70%+ acceptance rating and grade inflation through the stratosphere, so I can't relate to their 3.95 sgpa from poopstick university). There are no doctors/scientists/scientifically literate people in my family. They're immigrants, but I luckily dodged the "A+ or you're grounded for the rest of your life!" stereotype that a few of my cousins fell victim to. In many ways, their total lack of understanding for how med school apps work, what the MCAT entails, etc. is great; but in many ways, it's a very solitary existence having virtually no one be able to relate to my specific circumstances. Then again, that may not be a bad thing.
I'm essentially doing this entirely on my own. My only motivation has been and always will be the people I want to help. I see it as the best possible situation for someone to really test their interest in a career.
