What if our interests and passions are playing video games, football, and bar hopping?
Obviously doesn't apply to me since I have other interests, but I'm curious about that question.
If those are your true, fundamental interests, have fun and don't expect to get into med school.
I was being a little facetious, obvi. The "follow your heart" advice only works if you actually care about stuff related to health/care, helping people, service, etc.
But if it's not natural for you to want to help people now, is a switch going to flip when you get into med school? For someone who plans to be a doctor, helping people should be a close to the top of their interests and passions. Cause that's what doctors do.
If you don't naturally want to help people, that's ok. Just do some traditional pre-med activities, volunteering, etc, and train yourself to like it.
If your vision of the future expands beyond diagnosing and prescribing for individuals, to stuff like research and public health, or if you have a non-standard vision, one that's more ideological, radical, political, religious, etc, do something in those fields.
edit: at least that's my take on it. What do you think? how would you answer the OP?
