"Help people". Just once I'd like a premed to explain to me what the f*ck they think that means, and what the f*ck they think that has to do with the practice of medicine.
The concept of "helping people" is often considered a BS notion because many people believe that helping others is a purely altruistic desire.
This isn't the case. There is a very real mental reward for helping somebody out.
Have you ever opened the door for someone? Picked up a book somebody dropped? Do you ever plan surprise parties for your friends, or give your girlfriend unexpected flowers?
Have you ever put a penny in the "Have a penny, leave a penny, need a penny, take a penny" plate? Have you ever given a homeless guy your change?
Are these actions purely selfless? I think not. I think many people feel very good about performing such acts simply for the knowledge that they know they've been useful to someone, and that "good" feeling is repayment in and of itself. It feels good to do something and cause someone else, even a complete stranger, to smile with sincere gratitude.
So yes. "Helping people" is a very valid reason to go into medicine. On the other hand, the reason why it's not a good way to sell yourself to admissions committees is that "helping people" is what every profession does. From trash disposal, to restaurant service, to law, to tech support, to the medical profession. Anything you get paid for is usually something that involves helping others.
So if you really don't like helping others, then really no job is for you.
