Linda Ann’s Answer
In many families, it is expected that sons, especially the first born son, will follow in the occupational footsteps of the family.
Because of the investment in time to become a physician (typically 11 years here in the USA), you really should have a strong desire to become a member of the ‘healing community.’
Perhaps you can identify a university that has a strong film making program AND a strong pre-medicine program. Enter as a freshman with an ‘undeclared’ major. Then, take some courses during your first year of studies to determine a good fit for yourself by engaging with the faculty members and student groups.
You are young, the best time to explore prospects for your future. Good luck!!
